Filed:

Jun 3, 1999

Appl. No.:

09/325288

Inventors:

Mark E. Peters - Chapel Hill NC

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1730

US Classification:

707 9, 707102

Abstract:

A method, system, and computer readable code for validating that a document or executable to be served from a server is the same original document or executable placed on the server by the legitimate author or owner. Digital signatures are stored with each file available for serving from, or executing from, a server. When a file is requested by a user, the contents of the requested file are validated (i. e. authenticated) using this digital signature. If the validation does not succeed, the file is not served to the userâinstead, the user is told that the requested file was not found. A number of optimizations are defined, including caching validated files and/or caching computed digests.

International Classification:

H04L 900

US Classification:

713156, 713185, 707511, 707512, 382305

Abstract:

A technique for compressing certificate information for use in portable credit instruments having limited storage capacity. An end user certificate typically actually comprises a chain of certificates, as SET transactions require not only the end user certificate and its parent certificates. Each certificate in the certificate chain is compared to a template for that certificate, and the differences are stored. Redundant differences within each certificate are deleted, as are differences which may be derived from differences stored for other certificates in the certificate chain. The remaining stored differences are then recorded on an end user credit instrument, such as a smart card. Preferably, the certificate chain is then recreated for verification purposes before the card is issued. PER encoding may also be employed to further compress the certificate information to be recorded on the credit instrument.

International Classification:

H04Q 720

US Classification:

455458, 4554122, 455567

Abstract:

A method, computer program product, and system for answering a wireless telephone is provided. In one embodiment, the wireless telephone receives an incoming call and then determines whether the user has placed the phone in automatic call answering mode. If it is determined that automatic call answering has been selected by a user, then the phone answers the incoming call by providing the calling party with an indication that the user will take the call momentarily, such as by sending a voice message indicating that the user is busy but will take the call momentarily and instructing the calling party to not hang up. The phone also places itself into mute mode until the user has taken the incoming call to prevent the calling party from overhearing conversations that may be taking place around the user until the user has determined that it is convenient to take the phone call. In other embodiments, the wireless telephone allows the user to carry on conversations without speaking through selection of appropriate prerecorded or generated phrases.

Inventors:

Mark E. Peters - Chapel Hill NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06K 7/10

US Classification:

23546201, 235375

Abstract:

Methods of communicating product status information include maintaining a record of a product identification string associated with a product of a user, the product identification string being associated with a corresponding batch of the product. A batch status request is transmitted to a directory service maintaining batch status information at selected intervals and/or responsive to a user request and the requested batch status information for the product is received. The batch status request need not include personal information of the user. Related directory services, systems and computer program products are also provided.

Appl. No.:

10/911295

Inventors:

Jacquelle D. Leggett - Raleigh NC, US
Mark E. Peters - Chapel Hill NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06Q 30/00
G06F 17/30

US Classification:

705 26

Abstract:

The invention comprises a financial management program and one or more databases containing information on merchants and their products. The program interacts with the databases containing the product information to return the prices and availability of goods located in a designated area. The program compares prices from various merchants and displays the results to the consumer. The program also allows the consumer to compare the prices with a household budget and financial data, while keeping track of trends in the consumer's spending and buying habits.

Inventors:

Mark E. Peters - Chapel Hill NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 9/00

US Classification:

713156, 713170, 713171, 713175, 380 30

Abstract:

A technique permitting an X. 509 certificate to simultaneously support more than one cryptographic algorithm. An alternative public key and alternative signature are provided as extensions in the body of the certificate. These extensions define a second (or more) cryptographic algorithm which may be utilized to verify the certificate. These are not authenticated by the primary signature and signature algorithm in the primary cryptographic algorithm. These newly defined extensions are reviewed by a receiving entity if the entity does not support the cryptographic algorithm of the primary signature.

Abstract:

Techniques are disclosed for deterring theft of media recording devices. Input received from a sensor, or some portion of the input, is encrypted prior to storing a media file. A decryption key must be provided when the media file is to be played back. If the key is not provided, then the file is preferably still played back, but is played back in a degraded manner. For example, a background color or other filler may be rendered in place of the encrypted portion. Additional parts of the file may also be degraded during playback. By making the playback unpleasant for the listener/viewer, theft of the recording device will be much less desirable—yet recording can continue uninterrupted, thereby minimizing disruption to legitimate users. The disclosed techniques may also be used to deter theft of the recorded media.

Abstract:

A system and method for state-based execution and recovery in a payment system is presented. A payment system uses a state machine to track completed sub-tasks using a state progress identifier and completion state data. When a failure occurs, stored completion state data and the state progress identifier indicate the last successfully completed sub-task. As such, when the payment system resumes payment operation execution after a failure, the state machine retrieves the stored completion state data and state progress identifier, and resumes execution based upon the retrieved information. As a result, the payment system continues payment operation execution at a point as to not duplicate the payment operation's previously completed sub-tasks.
