A method of protecting a password being used to establish interaction between a user and an application includes detecting a request for the password from the application by receiving a notification from the user indicating the request. The method further includes combining the password with information identifying the application, so as to produce a protected password, and authenticating to the application using the protected password. The method may also include a mutual authentication capability between user and the application.

Improved techniques to partially encrypt media files are disclosed. The encryption serves to cryptographically secure only a portion of the media data within a media file, while the remaining portion of the media data is not cryptographically secured. Although only partial encryption is used, the portion being encrypted serves to substantially disrupt usefulness of other parts of the media file which are not encrypted. In other words, the partial encryption renders the media file substantially unusable by unauthorized users. In one embodiment, the partial encryption is performed by a host device and thereafter the partially encrypted media file is delivered to a client device. The client device, if authorized, can subsequently decrypt the partially encrypted media file and utilize (e.g., play) the media file. However, since the media files are only partially encrypted, the decryption is likewise also only partial, which makes decryption faster and less resource intensive.

A client-server authentication method for use where a server process has access to a repository storing cipher-protected client passwords. The method includes applying the same cipher function to the client's copy of its password as was previously applied to generate the stored cipher-protected client passwords. This ensures that both the client and server have access to an equivalent cipher-protected client password-providing a shared secret for driving a mutual challenge-response authentication protocol without having to convert the password into cleartext at the server. The invention can be implemented without significant additional software infrastructure in a UNIX environment. Client passwords are typically stored in the UNIX password repository under the protection of the crypt( ) function applied to the combination of the password and a random number (a "salt'). By sending the salt to the client system together with the server's initial challenge of the authentication protocol, a process at the client is able to apply the crypt( ) function to the client password with the same salt such that the client and server have a shared secret for use as, or to generate, a common session key for the authentication.

A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols.

A computer random access memory is divided into first and second partitions. Each partition has its own operating system (OS). The first partition has a conventional OS and is designated for non-Internet use. The second partition is designated for secure Internet access, and has an OS specific for Internet usage. Software in the second partition cannot write or copy files in the second partition. The size of the second partition is fixed and unchangeable while said second partition is open. Each software application in the second partition is allocated a memory region that cannot be changed, thereby preventing memory overflow attacks. A secure memory is designated for temporary storage of software used in the second partition. Cyclic redundancy check (CRC) values are calculated for all files in the secure memory. To detect unauthorized file changes, CRC values are calculated for all files used in the second partition, and checked against values stored in the secure memory. The second partition can write only to a secure memory using a security arrangement such as password protection or a download memory separate from the first partition to allow files stored in the download memory to be examined by scanning and testing from the first partition prior to being stored elsewhere in the computer.

A method, system, computer program product, and method of doing business by providing a provable chain of evidence for data stream(s) created by one or more components (such as input/output devices and application processing components). Components that create the evidence collection are authenticated. A unique identifier of each such component is included within cryptographically-protected information that is added to the evidence collection. A digital signature is preferably used for the cryptographic protection, thereby digitally notarizing the evidence collection. The authenticity and integrity of the evidence collection can be verified. In preferred embodiments, the authenticated identities of components providing the evidence can also be determined from the cryptographically-protected information. One or more data streams may be included within the evidence collection to establish information such as the date and time the evidence collection was captured, the geographic location where the capture was performed, an identification of a person performing the evidence capture, and so forth. When present in a provable chain of evidence, these types of additional evidence are provided by authenticated components which are identified within the cryptographically-protected information.

An electronic economic value representation distribution system. The potential user may specify the economic value representation. A password is required to lock in the representation and is stored in the issuer server. Information identifying the representation is linked to the password stored in the database. User can create the said representation by downloading from the issuer computer that may be printed on the user's printer connected to his personal computer. On presentation of the said economic value representation at verifier's terminal connected to issuer server, identifying data is transmitted to issuer server for verification. Upon successfully verifying said identifying information, user is requested to present the password locking the representation. Upon successful authentication of presented and successful reconciling with originating account, verifier is to provide user with services or amount valued by the economic representation.

A user generates a pattern in a matrix (or two-dimensional grid) and enters a user name and an associated password. This username, password and pattern are stored locally on a computing device or are transmitted to a remote computer server for later authentication. Upon authentication, an input matrix is displayed. The user enters the password into the matrix in the form of the pattern, and also enters the username. The computer retrieves the previously stored pattern and password with the username. The previously stored pattern is used to read the input password from the input matrix. A match with the stored password indicates authentication. Alternatively, the input matrix only includes the pattern and password is entered separately. The input matrix may also be filled with random characters to improve security. The stored pattern is compared to the input pattern using image analysis or by comparing a set of coordinates.
