Jun 27, 2002

Appl. No.:

10/187734

Inventors:

Chunman Yu - Sunnyvale CA
Brian Metzger - San Jose CA
David W. Nguyen - San Jose CA
Girish Dixit - San Jose CA

Assignee:

Applied Materials, Inc. - Santa Clara CA

International Classification:

C25D 2100

US Classification:

205 81, 204400, 204434, 205775, 205787

Abstract:

Embodiments of the invention provide an electro-analytical method for determining the concentration of an organic additive in an acidic or basic metal plating bath using an organic chemical analyzer. The method includes preparing a supporting-electrolyte solution, preparing a testing solution including the supporting-electrolyte solution and a standard solution, measuring an electrochemical response of the supporting-electrolyte solution using the organic chemical analyzer, and implementing an electro-analytical technique to determine the concentration of the organic additive in the plating bath from the electrochemical response measurements. The method is performed for independently analyzing one organic additive component in a plating bath containing multi-component organic additives, regardless of knowledge of the concentration of other organic additives and with minimal interference among organic additives.

G06F 11/30

US Classification:

713193000, 713151000, 713182000

Abstract:

A system and method for a mechanism is provided for automatically selecting a new encryption key for re-encrypting data in a target database. New initialization vectors may be specified for re-encrypting each column of data selected for re-encryption. Further, a new initialization vector may be specified for one or more rows of data of a database table in the target database that is selected for re-encryption.

International Classification:

H04N 7/16

US Classification:

726029000

Abstract:

A system and method for allowing application programs that are external to the relational database to access the sensitive data in the database in a seamless fashion are described. The application programs are allowed to use existing query statements without having to modify such statements for accessing encrypted data in the relational database.

Assignee:

SafeNet, Inc. - Belcamp MD

International Classification:

H04L 9/32

US Classification:

713167

Abstract:

A novel approach introduces an extra layer of data security by storing files and the keys required to access the files separately. When the files are being accessed, the host of the files sends a request to an access device that stores the keys to access the files. The key will be provided to the host only if at least one of the following conditions is met: the host is within close proximity of the access device, the identity of the person attempting to access the files is authenticated, or the security status of the host is verified.
