Abstract: A method and system for analyzing scripts. A script is processed, which executes text blocks of code derived from the script and copied to an output file in a sequential order. The script is the first text block that is copied to the output file. Executing the text blocks includes interpreting each text block to generate and execute a corresponding interpreted block of code. Processing the script results in the text blocks being sequenced in the output file in the sequential order. The text blocks include an original text block of code that includes text that may be directly inferred from text appearing in the script. The blocks of code include a new text block of code, which includes text that may not be directly inferred from text appearing in the script. The new text block is generated from executing the original text block.

Abstract: A trusted rendering system for use in a system for controlling the distribution and use of digital works. A trusted rendering system facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output. The watermark data typically provides information relating to the owner of the digital work, the rights associated with the rendered copy of the digital work and when and where the digital work was rendered. This information will typically aid in deterring or preventing unauthorized copying of the rendered work to be made. The system for controlling distribution and use of digital works provides for attaching persistent usage rights to a digital work. Digital works are transferred between repositories which are used to request and grant access to digital works.

Abstract: This specification describes technologies relating to imparting real-time priority-based network communications in an encrypted session. In general, aspects of the subject matter described can be embodied in methods that include establishing, based on cryptographic information in a reserved, random-data portion of a handshake communication, a session, receiving parameter values relating to a sub media stream, included in a header of a network communication, storing the parameter values, obtaining state information and a data payload included in a second network communication, identifying, from the state information, a purpose of the second network communication, and whether a header of the second network communication includes one or more new values corresponding to one or more of the parameters, updating one or more of the stored values based on the one or more new values, and processing the data payload based on the identified purpose and the stored parameter values.

Abstract: A method for controlling access to content by an Acquisition Point to Presentation Points in clusters in a domain. The AP receives from a PP an access content request comprising the PPs cluster identity and the PP's priority. The AP verifies if access is granted to a PP in the cluster and, if so, grants access to the requesting PP. If not, the AP verifies if access is granted to PPs in a maximum number of clusters. If not, the AP grants access. If the maximum is reached, the AP verifies if the requesting PP's priority is higher than the priority of every PP in another cluster. If not, access is denied; if so, the AP grants access to the requesting PP and denies access to the PPs in the cluster with the lowest priority values. An Acquisition Point is also claimed.

Abstract: A method of managing access rights in a smart card, to subordinating execution of a command (Cmd1, Cmdk) such as reading or writing to an event (Evt1?, Evtk?) being valid, such as authentication by verifying a code. The state of validation events is stored in a register, and the access rights are stored in a command list (List_Cmd) made up of couples (Cpl1, Cplk), each associating a command with an event. On receiving a request to execute a command, a search is made in the command list (List_Cmd) for the couple (Cpl1, Cplk) that includes the requested command, and execution is refused if the search is unsuccessful. If the search is successful, then it is determined from the register (referred to as the card security state register) whether the event associated with the command is or is not valid, in order to authorize or refuse execution thereof. The invention is for use in any smart card application that involves access rights.

Abstract: To allow a user to access a public data network from a region of service operated by a visited access provider, the visited provider is supplied with an identity of a credit provider. The user is redirected to the credit provider, resulting in establishment of a temporary connection with the credit provider. During this temporary connection, the user supplies original user credentials and, in return, receives substitute user credentials if the original user credentials are valid. The substitute user credentials are supplied to the visited provider, which proceeds to have the user authenticated by the credit provider on the basis of the substitute user credentials. In this way, the visited provider authenticates the user with the credit provider before allowing the user to access the public data network, but a secure exchange of the original user credentials between the user and the credit provider prevents unauthorized access to this information by the visited provider.

Abstract: A method for an impaired user to control a peripheral device including receiving key-value pair input from the user, determining whether the received input is valid and executing a job generated from the valid received key-value pair input.

Abstract: A scalable method and apparatus that detects frequent and dispersed invariants is disclosed. More particularly, the application discloses a system that can simultaneously track frequency rates and dispersion criteria of unknown invariants. In other words, the application discloses an invariant detection system implemented in hardware (and/or software) that allows detection of invariants (e.g., byte sequences) that are highly prevalent (e.g., repeating with a high frequency) and dispersed (e.g., originating from many sources and destined to many destinations).
