  • Adaptation of service applications to heterogeneous execution context by means of smart cards
    Patent number: 6862614
    Abstract: Service applications are provided on multiple types of devices with different execution contexts. A smart card stores the application description, and processes it to install an adapted configuration of the application for whatever device it is inserted in. Smart cards are compatible with many devices, as well as being small, resistant, and tamper-proof. In addition to security features, their processing capacities can be used to at least partially treat the abstract descriptions of the applications in order to produce concrete descriptions adapted to the execution context.

  • Secured method for monitoring the transfer of value units in a chip card gambling system
    Patent number: 6851607
    Abstract: A secure system and method for the transfer of value units between a plurality of gambling cards (CJ) and a plurality of gambling machines (200, 300). Each machine has a transcriber (210, 310) to debit value units of the gambling cards. The machines are connected via a secure network (123) to a central processing unit (1). Each gambling card (CJ1) stores data (S, Op1, Op2, Opx, Id, S) unique to the card and the use of that card in gambling. The central processing unit (1, BD) stores the same data as what is in the cards. The cards' and the CPU's data are maintained in parallel as the gambling progresses, and may include data from previous sessions. A monitor (BD) checks that the CPU (1, BD) data and the card (CJ1) data correspond. Thus the integrity of this smart card gambling is enhanced.

  • Biometric identification method and device adapted to verification on chip cards
    Publication number: 20050011946
    Abstract: A method and associated device for checking a biometric signature by a simple and secure calculation adapted to personal objects of the chip card type. The method is based on the storage within the object of an obscured biometric signature and an associated authentication code. A terminal capturing a fingerprint compares the fingerprint data with the obscured biometric signature transmitted by the card and transfers the result of this comparison to the chip card, which validates this result with the authentication code.

  • Authenticating method between a smart card and a terminal
    Patent number: 6839840
    Abstract: The invention concerns a method enabling a smart card and a terminal whereto it is connected to authenticate each other. The invention is characterized in that at the end of each transaction the terminal calculates, from data representing the card at said transaction end, a secret code CSC2 which is recorded in a zone ZCSC with unprotected access in the card memory and an authentication certificate CA2 which is recorded in a zone ZCA with protected access of the memory by presenting a secret code CSC2. At the next transaction, the terminal calculates, by means of data contained in the card, a secret code and an authentication certificate which are compared to those previously recorded to perform authentication. The invention is applicable to smart cards.

  • Migration of different source languages to an execution medium
    Patent number: 6810518
    Abstract: The invention automatically executes, in a single execution medium, a number of programs written in source languages to which respective execution media are dedicated, without constraining a programmer to a single source language for a respective execution medium type. Each program is compiled into a program expressed in an intermediate language representing a minimum subset of the source languages. In a data processing means such as a smart card, an execution medium is dedicated to the intermediate language. The intermediate language program is loaded with a respective programming library adapting the respective source language to the intermediate language in order to execute the intermediate language program in the execution medium.

  • Generic communication filters for distributed applications
    Patent number: 6807561
    Abstract: A mechanism is provided that enables an application to interact directly with certain types of communication messages, while at the same time retaining the advantages of a semantics-based framework, such as remote method invocation. A set of standard entry points are defined that can be employed by any application to receive and interact with communication messages. In one implementation of the invention, three such entry points are established as invokable methods that are called within the application. These three methods respectively relate to data processing operations, pre-processing operations and post-processing operations.

  • Chip card equipped with a counter device
    Patent number: 6698661
    Abstract: In order to render a chip gratuity counter more flexible, the invention consists in recording in the chip card memory a file architecture to facilitate the management of its counters. Said architecture is characterized in that a counter unit file, wherein are located the counters relative to an application, is associated with rules which are applicable thereto. Thus, the simple designation of a counter unit implies the implementation or rules applicable to the counters on the counter unit. The implementation is internal to the chip card and does not require any exchange with the reader. The chip memory further comprises the rules file, the conditions file and the computing file the interaction of which provides greater flexibility of use.
