To provide system access to physicians, physician staff, and clinicians To protect the confidentiality of patient and administrative information To maintain system integrity and security as defined by the organization To comply with HIPAA regulations as set forth by the Federal Government Any clinician requesting access to the Hospital Information System (HIS) system will notify the Information Services (I.S.) Department. An information packet will be sent to the requesting clinician. This packet will include Request forms, profile questionnaire, security policy, and hardware/system requirements Once the request form and questionnaire have been returned to I.S., user codes and passwords will be defined. A signed confidentiality statement will be obtained and kept on file in the I.S. department. Under no circumstances should this code be shared with anyone else. All computer transactions are traced through this code and is audited daily by the Information Services Department. You will be responsible for all inquiries made under your security code. Patient information in the organization’s computer system is to be kept confidential and private as per HIPAA and Florida State regulations. Health care organizations have toiled for years to implement policies and procedures to comply with the HIPAA Privacy Regulations. April 14, 2003 has come and gone, and HIPAA Privacy is no longer a questionable regulation, it is a reality. No matter how much you would like to take a break from HIPAA, there is still work to be done. get really disheartened when I heard most arguments urging attorneys to encrypt their e-mail. For several years now, I've heard selected attorneys and consultants say "e-mail can be intercepted," "people are interested in reading YOUR e-mail," "e-mail is like a postcard," "there are malpractice concerns associated with transmitting unencrypted e-mail," or "e-mail interception happens all the time -- people are just to embarrassed to admit it." These arguments typically attorney client security conclude that given one or more of these risks (perhaps called "facts"), attorneys should encrypt their e-mail communications. End of story. What standard of encryption is good enough for HIPAA? Well, the new HIPAA Security Rule seems to leave the choice up to you. Good enough encryption for HIPAA should mean that the software employs time-tested encryption algorithms which can't be penetrated by someone with dedicated tools or governmental deciphering resources, if at all. Examples of these are DES, AES, RSA, Blowfish, Twofish. No algorithm GUARANTEES total security against the various types of security attacks that professional hackers can employ (see Adam Benrent's paper But "good enough encryption" for your purposes is available in a plethora of free or cheap products, including my personal favorites: The problem with this story is that it is incomplete, thereby failing to educate properly the audience it is intended to help. Attorneys are told that encryption is the answer to deal with the real threat their client confidences and secrets will be disclosed. Unfortunately, attorneys are left to their own devices to plan and implement encryption (and hopefully other measures) to address the overarching security issues associated with protecting client confidences and secrets. What level of encryption is appropriate? Will it work with the attorney's system (perhaps better to say systems) and all clients' systems? Is it foolproof? How do I manage the keys within my organization? How do I recover encrypted files after someone leaves within the organization? How can encryption be implemented in [fill in the blank (my organization -- governmental agency, pro bono referral network, legal services agency, corporation, corporate law firm, shared office space, …)]? Like most technical issues, the issue of whether to adopt encryption is not so simple. There are a host of issues associated with attorney client security integrating a technical solution into an existing corporeal practice. Perhaps the most important issue attorneys need to understand is that encryption products are simply software. As such, they cannot possible be the only answer to real or perceived threats to the security of client confidences and secrets. To quote Bruce Schneier, author Secrets & Lies: Digital Security in the Networked World, "If you think technology can solve your security problems, then you don't understand the problems and you don't understand the technology." Secrets & Lies (J. Wiley & Sons 8/2000) at xii.1 Encryption -- or any technology for that matter -- is only effective only if it is treated as part of a much larger process. Here, I reflect on some of the issues that attorneys should consider as they delve into the encryption issue. Before I begin, three points to provide some context. E-mail may be an efficient and cost effective way of transmitting data, but how secure is this method of information distribution? Many e-mail messages contain information that could be regarded as sensitive by either the sender or the receiver. In the case of the health care industry, messages may even include Electronic Protected Health Information (ePHI). ePHI is defined as being individually identifiable information that is maintained in any form by a health plan, clearinghouse, or provider and related to health condition, treatment, or payment. The Health Insurance Portability and Accountability Act (HIPAA) requires health care institutions to comply with information privacy and security standards. Many of these institutions have drafted policies that forbid the transmission of protected health information via e-mail. Other institutions which have local area networks have permitted the transmission of protected health information, but only to other employees on the institution’s local computer network. While neither the HIPAA privacy nor security rule expressly requires it, most security professionals believe secure Internet e-mail is a reasonable step for a health care institution to take in order to abide by the HIPAA requirement to “ensure the integrity and confidentiality” of ePHI. (i) I do not propose any easy solutions to the encryption issue. I intentionally raise more questions than I answer. The reader should come away asking questions instead of blindly following encryption advocates and relying upon encryption products. (ii) I like encryption products. They have appropriate -- and sometimes necessary -- uses. I believe that encryption products can be powerful tools that go a long way to help protect client confidences and secrets when (1) those products and associated processes/procedures are thoughtfully integrated into an attorney's practice; (2) those products and those processes/procedures are thoughtfully integrated into a client's business or situation; and (3) both sets of products and processes/procedures are thoughtfully implemented and maintained by all parties. In short, when a security protocol partly based on encryption products is integrated into one's practice after careful consultation with one's clients, it can be a powerful solution. If encryption products are integrated into an attorney's practice in the absence of any consideration of larger security processes followed by the attorney or organization, they can be dangerous tools. (iii) I take as a baseline assumption that e-mail is not secure. The reader should as well. Snooping and interception are realities, regardless of the amount of money involved. It is relatively easy to gain access to computer systems. If you want a "parade of horribles" relating to the lack of security on the Internet or relating to computers generally, pick up Schneier's Secrets & Lies. It provides the necessary examples and context. The analogy to a postcard does not. Get Some Ethical Perspective "Confidential client information must be 'acquired, stored, retrieved, and transmitted under systems and controls that are reasonably designed and managed to maintain confidentiality.'" ABA 99-413 n.4, quoting Restatement (Third) of the Law Governing Lawyers, §112, Cmt. d (proposed official draft 1998). Some attorneys and reporters look to ABA 99-413 as "the answer" on encryption. It is not. ABA 99-413 does not say that you do not need to encrypt your e-mail. In ABA 99-413, the ABA Standing Committee on Ethics and Professional Responsibility simply took a comparative look at the issue of how to protect client confidences and secrets that are transmitted by e-mail. The Committee found that transmission of unencrypted e-mail after consultation with the client advising the client of the risks involved was a reasonable way to exchange client information.2 Importantly, the Committee considered the fact that there are risks associated with the way attorneys handle other forms of client communications. The reader should too. The latest ethics opinions issued to date in the jurisdictions that have addressed the issue seem to agree with the overall reasoning of ABA 99-413. I do too.3 As suggested below, an alternative approach would be, for most attorneys and clients, undesirable and unreasonable given its logical extension. best way to hide pictures Sort by Area Hide Photos files, folders, and drives so you can encrypt, decrypt, wipe files and folders with right-click ease able to encrypt photos or drawings contained in a text file Encrypt, File Encryption, Encrypting, Encrypt files, Self decrypt ... pictures,download picture, File Encryption, Data Encryption, personal Encryption, Message Encryption, E-Mail Encryption, E mail Encryption, email encryption, download photo, download photos, Picture Encryption. search picture Encrypt photos so that unauthorized eyes cant see them You can encrypt your photos to prevent viewing by unauthorized people you can encrypt email you send to them by clicking on the encrypt button. you are only able to encrypt this email if you have the public key of the recipient.

Flemish Personality Award CaStaR - Personality of the year Because of Rijndael's selection as AES, we have been selected as (Flemish) personalities of the year. As a consequence, we were rewarded with the piece of art you see on the right. The colored specks on the skull and the bones are in fact the shields of a rare beetle. Some people say it symbolizes the DES (bird) being replaced by the AES (skull). Others think that the Flemish watch too much MTV. What is Rijndael Rijndael is a block cipher, designed by Joan Daemen and Vincent Rijmen as a candidate algorithm for the AES The cipher has a variable block length and key length. We currently specified how to use keys with a length of 128, 192, or 256 bits to encrypt blocks with al length of 128, 192 or 256 File Encryption, Data Encryption, personal Encryption, Message Encryption, E-Mail Encryption, E mail Encryption, email encryption, bits (all nine combinations of key length and block length are possible). Both block length and key length can be extended very easily to multiples of 32 bits. Rijndael can be implemented very efficiently on a wide range of processors and in hardware. The design of Rijndael was strongly influenced by the design of the block cipher Square .Publications Besides the documents available from this web site, a number of (technical) Rijndael-related papers have been published.

Rijndael is used in the digital lecture board, developed at the university of Mannheim. It is also used in a freeware file protection tool called FIVE.More information and analysis The NIST AES site contains a multitude of reports covering more topics of the AES/Rijndael than we would have thought possible. Prof. J. von zur Gathen organized two Rijndael seminars at the university of Paderborn (Germany). A lot of interesting material was developed, and File Encryption, Data Encryption, personal Encryption, Message Encryption, E-Mail Encryption, E mail Encryption, email encryption, is available here. Rijndael FAQ How is that pronounced If you're Dutch, Flemish, Indonesian, Surinamer or South-African, it's pronounced like you think it should be. Otherwise, you could pronounce it like "Reign Dahl", "Rain Doll", "Rhine Dahl". We're not picky. As long as you make it sound different from "Region Deal".Why did you Picture Encryption. choose this name Because we were both fed up with people mutilating the pronunciation of the names "Daemen" and "Rijmen". (There are two messages in this answer.) Can't you give it another name ? (Propose it as a tweak Dutch is a wonderful language. Currently we are debating about the names "Herfstvrucht", "Angstschreeuw" and "Koeieuier". Other suggestions are welcome of course. Derek Brown, Toronto, Ontario, Canada, proposes "bob".Rubberhose transparently and deniably encrypts disk data, minimising the effectiveness of warrants, coersive interrogations and other compulsive mechanims, such as U.K RIP legislation. Rubberhose differs from conventional disk encryption systems in that it has an advanced modular architecture, self-test suite, is more secure, portable, utilises information hiding (steganography / deniable cryptography), works with any file system and has source freely available.Using linux, putting a deniable file system on a USB memory device, leaving no trace in the host should not be tricky as an initial problem. FUSE (the user land file system) would seem to be a likely candidate.The more difficult problem is the secondary one. How can I be sure that no traces of the data in the deniable filesystem remain in the host after I remove the USB device? There are a few obvious areas of concern - swap file, automatically written backups (generated by editors, etc.) that might be written in the users home directory in a resident file system, etc.One way to start might be to chroot to a normal file system on the USB device, and then mount the deniable system also on that device. This would leave swap and possibly incriminating entries in log files. Swapping could be disabled as well as loggingI've been using this product, http://www.truecrypt.org/, it has two levels of 'plausible deniability'. Using hidden volumes and volumes are not identifiable as truecrypt volumes, just random data.If the mere existance of encrypted data can is some places and or circumstances be taken as incriminating evidence, then surely the existance of the rubberhost kernel modules might also be hazardous.If you are only going to use the rubberhose data on a small set of known machines, the the modules could be installable, which would solve the problem.On the other hand, following up on the USB idea, the advantage here is that one might, for instance, slip into a random internet cafe, do whatever, and leave. This disallows installable kernel modules. It is true that at this time, I doubt that internet cafes will have linux - especially linux with FUSE support, but this may be changing.Overall, a complete linux running in userland stored on USB may be the more practical approach.Until the popular operating systems put random noise onto empty disk sectors instead of zeros, all of these methods will still point to the use of encryption. I have used truecrypt and like it for some applications. But I don't think I would recomend it to someone who would be jailed if they were found to be in possesion of encrypted data.Later versions of FreeBSD provides native support for an encrypted filesystem, along with some additional steganography which, supposedly, can masquerade the encrypted filesystem as unencrypted data.It is all done within the "Geom Based Disk Encryption" (gbde)-framework, described here:There is a device that kinda does this. It's called a Blackdog. It's about the size of a credit card, 10 cards thick. It has a fingerprint reader, and an PPC/FPGA running linux. That is, processes run outside the OS of the "host PC". It's a weird device that isn't very secure, but it's a good start and great idea.Basically, you create an "outer" encrypted volume (we'll call it 'O'). You put a few files in it that aren't really all that important, and protect O with a passphrase.Then, using some of the free space on O (which is random bits), you create an "inner" volume ('I'), which *looks* like random bits. Nothing about O gives any clue as to the existence of I -- you have to know I is there to even attempt to use it.The idea is that if someone captures your filesystem, you might be forced under duress to give up the passphrase for O, but could still keep the existence of I hidden.In principle, however, the fact that TrueCrypt has this function is public knowledge, and therefore keeping I a secret isn't trivial. If detained by "legal" police, you might have deniability -- it would be hard for them to prove you have an I volume.If detained by the secret police, however, one would be questioned about the use of this feature, and such (hopefully hypothetical) illegal organizations are willing and able to "extract" such information (e.g. through the use of sodium pentathol).Jetico's BestCrypt product also offers hidden containers. I haven't tried using them though, I've always been afraid of getting my drives confused and writing to the container holding the hidden container and accidently damaging/destroying the hidden container and its contents.Indeed, invisibility is key.Just like the 'ZoneAlarm' method. Why protect a 'known computer'? Everything can be compromised (in the end with bruteforce)Simply make the computer invisible.because things that do not exist cannot be comprommised.Rubberhose was always clunky, but the major feature it had, which TrueCrypt doesn't, is the unprovability that there are any further layers of encryption. As physical torture becomes less useful if the victim can plausibly deny any further layers...Thus the name Rubberhose When everyone has security tools, then having security tools won't mark you as a criminal.
