Appl. No.:

09/952290

Inventors:

David Lordemann - Los Altos CA, US
Daniel Robinson - Santa Clara CA, US
Paul Scheibe - Woodside CA, US

International Classification:

H04L009/00

US Classification:

713/201000

Abstract:

A method and system for protecting objects stored on network servers are presented. An object server runs computer software that designates which objects are to be protected and the security policy for that object. If the object server receives a request for a protected object, the object server creates an enhanced request containing encrypted data related to the request and the requested object; this enhanced request is redirected to a security server which authenticates the request, retrieves the requested object, encrypts the object using a one-time encryption key, and combines the encrypted object with mobile code, the security policy, and object controls to implement the policy. This package is then sent to the requester, which executes the mobile code, resulting in the instantiation of the security policy and object controls on the requester computer. The mobile code will execute tests to ensure proper instantiation of the object controls. A one-time decryption key may be requested by and provided to the requester providing the object controls were properly instantiated. The requested object is rendered subject to the security policy and object controls.

US Classification:

713/201000

Abstract:

A system and method for establishing a log file which may be used to create an audit trail are presented. A security server maintains a log file of actions performed by a requester and the security server which are related to protected objects. Object controls instantiated with the object on the requester device transmit an encrypted descriptor of the action to the security server and may prevent the requester device from taking any action (viewing, editing, printing, etc.) if there is no secure connection to the security server. The security server will record the information received from the requester device, along with other data, to the log file as well as recording a descriptor of any of the security server's actions taken which relate to the protection of objects.

Abstract:

A method and system for protecting objects stored on network servers are presented. An object server runs computer software that designates which objects are to be protected and the security policy for that object. If the object server receives a request for a protected object, the object server creates an enhanced request containing cryptographically protected data related to the request and to the requested object; this enhanced request is redirected to a security server. The security server authenticates the request, retrieves the requested object from the object server, a file server associated with the security server, or a local cache, encrypts the object, and combines the encrypted object with mobile code, the security policy, and object controls to implement the policy. This package is then sent to the requester, which executes the mobile code, resulting in the installation of the security policy and object controls on the requester computer. The requested object is rendered subject to the security policy and object controls. The security server maintains a logfile of actions taken on the object. This logfile can be used to create an audit trail for the object.

Abstract:

A computer-implemented method comprises receiving, by a processor, search requests to search a database; receiving a reindex request to reindex information in the database based on a new ontology for the database or a new number of shards for a first index server; initiating, by the processor, generation of a second index for the database while a first index managed by the first index server continues to be used live for responding to received search requests; completing the generation of the second index during a certain period when no search request is sent to the first index server; and in response to the completing, using the second index live for responding to received search requests.

Abstract:

Systems and methods for live reindexing include receiving, at a dispatch server, a request to reindex a database, wherein, at the time the request to reindex is received, the dispatch server is configured to send queries for information in the database to a first index server, the first index server comprising a first index of information in the database. The systems and methods further include, responsive to receiving the request to reindex and while the database is live, generating a second index of the information in the database, storing the second index at a second index server, and configuring the dispatch server to use the second index server as a live index server and to no longer use the first index server as a live index server.
