Inspection of playing cards
A playing card integrity checker utilises a blue light source to illuminate the playing face of each card to use template matching to identify the value and suit of each card based on stored templates from cards of the same card manufacturer. This information and the number of cards counted is matched against the cards needed for a predetermined game. The absence of required cards or the presence of superfluous cards is reported. Cards that have their faces reversed or appear marked are also reported.

Establishing a trusted platform in a digital processing system
InactiveUS20060015717A1User identity/authority verificationUnauthorized memory use protectionDigital signal processingOperational system
A trusted platform in a digital processing system is maintained even when modules, or other processes or data, are loaded after a boot sequence. A configuration file is used to include measurements (e.g., hash values, signatures, etc.) of modules to be loaded. After secure boot-up the operating system kernel uses the configuration file to check module integrity prior to loading and executing. If a module does not verify against the configuration file data then the system can prevent further operation, restrict certain operations, indicate the non-trusted nature of the system or take other actions. In one embodiment, if a module does not pass the integrity check then the failed measurement is extended into a specific Platform Configuration Register (PCR) within a Trusted Platform Manager (TPM) process. Subsequently, client applications can determine if the platform is trustable based on the return of the PCR value. A local application (application running in the same platform) can “seal” secrets to a trusted platform. The operation of the application relies on the secrets, which can only be revealed in a trusted platform.

The invention discloses a method, device and system of authentication and service calling, used for realizing legality authentication of an authentication server in a service platform to a client side application and promoting the safety reliability of a calling mechanism of a platform capacity API (Application Programming Interface). The authentication server realizes the safe distribution of a clientKey by displacing a test authentication module in the client side application to a client side authentication module preset with an MAC (Media Access Control) fingerprint and the clientKey. When the client side application satisfies a trigger condition, the client side authentication module firstly passes an integrity check based on an MAC fingerprint mechanism and applies for registration to the authentication server based on an MAC1 generated by the shared clientKey and obtains a random authentication factor. When the client side application needs to call the platform capacity API, a dynamic token is generated based on the authentication factor to be carried in a service request. After the dynamic token authentication passes, the platform capacity API is allowed to be called.

InactiveUS6963976B1Low costSame level of securityData processing applicationsEncryption apparatus with shift registers/memoriesComputer hardwareCiphertext
The present invention provides encryption schemes and apparatus which securely generate a cipher-text which in itself contains checks for assuring message integrity. It also provides compatible decryption schemes confirming message integrity. The encryption scheme generates a cipher-text with message integrity in a single pass with little additional computational cost, while retaining at least the same level of security as schemes based on a MAC. One embodiment encrypts a plain-text message by dividing the plain-text message into a multitude of plain-text blocks and encrypting the plain-text blocks to form a multitude of cipher-text blocks. A single pass technique is used in this process to embed a message integrity check in the cipher-text block. A message integrity check is embedded in the cipher-text blocks by embedding a set of pseudo random numbers, which may be dependent, but are pair-wise differentially uniform. We also describe an embodiment which is highly parallelizable.

Programmable cellular telephone and system
InactiveUS6018656ARadio/inductive link selection arrangementsAutomatic exchangesCode moduleUser input
A module (P-code module) provides parameter information to a Number Assignment Module (NAM) in a cellular phone unit by processing a simple programming code (P-code) entered by the user through a telephone keypad. The P-code employs a flexible length telephone keypad coding that can be translated into programmable parameters of cellular phone products. Field identification numbers and look-up tables are used to shorten the P-code length for more frequently used information. To activate a cellular phone, the user provides product and serial number information to a dial-up access center which then generates a scrambled P-code for entry by the user. The P-code module within the processor unit of the cellular phone likewise descrambles, decompresses, and performs an integrity check on the sequence of digits being entered by the user. Activation information is then provided by the access center to the manufacturer of the cellular phones in order to plan future production, target marketing and track dealer inventory.

A processing system is set forth that includes a processor, read only memory storing an operating system image file accessible by the processor, and random access memory that is also accessible by the processor. The processing system also includes a boot program that is executable by the processor to initialize the processing system in response, for example, to a power-on event, reset event, or a wake-up event. A power-on event occurs when power is initially provided to the processing system while a wake-up event occurs when the processing system is to exit a low-power mode of operation. A reset event occurs when, for example, a fault is detected that causes the system to restart. The boot program selectively performs a full boot copy of the operating system image file from the read only memory to the random access memory or a fast boot copy of only predetermined portions of the operating system image file from the read only memory to the random access memory. For example, the boot program may execute the full boot copy operation in response to the power-on event and the fast boot copy operation in response to the wake-up event and / or reset event. Further, the boot program may limit execution of the fast boot copy operation to those instances in which the random access memory passes an integrity check of the contents of one or more areas containing selected portions of the operating system copied from the read only memory during a prior full boot copy operation.

Method and apparatus for managing data compression and integrity in a computer storage system
A storage system stores discrete data units and corresponding metadata. The storage system receives data for storage, calculates a first hash value for the data, and identifies a set of compression conditions that correspond to a client ID associated with the data. When the compression conditions indicate that the data should be compressed, the data is compressed to create compressed data. Following compression of the data, the storage system calculates a second hash value for the compressed data, and stores the second hash value in the metadata, while also retaining the first hash value in the metadata. The storage system stores the compressed data, and deletes the uncompressed version of the data. An integrity check of the data stored in the storage system can be carried out periodically using the first or second hash values contained in metadata for each discrete data unit.
