A privacy-preserving index system addresses the problem of providing a privacy-preserving search over distributed access-controlled content. Indexed documents can be readily reconstructed from inverted indexes used in the search. The privacy-preserving index system builds a centralized privacy-preserving index in conjunction with a distributed access-control enforcing search protocol. The privacy-preserving index utilizes a randomized algorithm for constructing a privacy-preserving index. The privacy-preserving index is strongly resilient to privacy breaches. The privacy-preserving index system allows content providers to maintain complete control in defining access groups and ensuring its compliance, and further allows system implementors to retain tunable knobs to balance privacy and efficiency concerns for their particular domains.

A new search protocol uses a message which a router periodically transmits onto the local LANs connected to its ports, and in response to the new protocol, all end stations receiving the message transmit their addresses to the router. The addresses transmitted to the router comprise the addresses and any other information needed by the router to reach the end station. For example, for an Ethernet LAN the layer 2 or MAC layer address of the end station is transmitted to the router. In the event that the protocol of the LAN uses source routing, the information transmitted to the router includes both the MAC address and the Route Information Field of the end station. In any event, the router uses the information received from the end stations to build its routing table. Then, upon receipt of the next CANUREACH message from a peer router, the desired destination end station will appear in the router's routing table, and there will be no need to waste bandwidth by transmitting search messages looking for the end station. The new protocol messages are transmitted periodically in order to keep the routing tables current is as the network changes dynamically.

The invention relates to a system and a method for service of video contents. A video loading node and the video service node adopt a P2P protocol to form a P2P-CDN network. The CDN network is divided into a plurality of assignment service areas; each client is allocated with an assignment CDN node; the video client is connected with an assignment CDN node through the network. When a user requests media displaying, the video client sends media search information to the assignment CDN node according to a P2P search protocol. The assignment CDN node selects a service node in the whole P2P-CDN and returns the node to the client. The client generates a media service request toward the service node and builds up a control link with control units and a plurality of data links with a plurality of media units, and media data is requested through the links. The invention solves problems such as scale expansibility of the CDN network, enhances the reliability of the system and reduces the maintenance cost of the system.

A system and method for detecting, analyzing, and controlling the content of computer files and information in a variety of formats, including embedded information. The system examines one or more computer files in their entirely, including any embedded files, objects, or data, looks of confidential or secret information according to an established security search protocol, which may vary from user to user. Objects in a computer file are identified and decomposed into component objects. This process can be repeated until a user-specified depth of decomposition is achieved, or until the component objects can no longer be decomposed. The component objects are then analyzed for specific content, which is displayed for review by the user. The user can then make decisions regarding removal or modification of that content before sending the file on for further processing or delivery to a recipient. A certificate file linked to the computer file documents the results of the analysis and any deletions or modifications, and can be stored in a central database. Files also may be given a risk score based on the occurrence of certain objects, data, or keywords in a file, based on type and location.

Described is a system for secure database searching. The system comprises a client-server architecture which allows a client to securely search a database of records possessed by a server. A database query is generated by the client and transmitted to the server. The database query is processed by the server using a privacy-preserving search protocol. An encrypted match result is produced by the server without decrypting the database query. The encrypted match result is sent to the client, and the client decrypts the encrypted match result to obtain a set of block identifiers representing blocks of records in the database that match the database query. The client obtains a block of encrypted records containing match results using only the set of block identifiers. The match results are decrypted by the client using a key obtained from the server. The unencrypted match results to the database query are then output.
