A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Secure data parser method and system

A system ( 120 ) detects transmission of potentially unwanted e-mail messages. The system ( 120 ) may receive e-mail messages and generate hash values based on one or more portions of the e-mail messages. The system ( 120 ) may then determine whether the generated hash values match hash values associated with prior e-mail messages. The system ( 120 ) may determine that one of the e-mail messages is a potentially unwanted e-mail message when one or more of the generated hash values associated with the e-mail message match one or more of the hash values associated with the prior e-mail messages.

Hash-based systems and methods for detecting and preventing transmission of unwanted e-mail

The systems and methods of the present invention provide a solution that makes data provably secure and accessible—addressing data security at the bit level—thereby eliminating the need for multiple perimeter hardware and software technologies. Data security is incorporated or weaved directly into the data at the bit level. The systems and methods of the present invention enable enterprise communities of interest to leverage a common enterprise infrastructure. Because security is already woven into the data, this common infrastructure can be used without compromising data security and access control. In some applications, data is authenticated, encrypted, and parsed or split into multiple shares prior to being sent to multiple locations, e.g., a private or public cloud. The data is hidden while in transit to the storage location, and is inaccessible to users who do not have the correct credentials for access.

Systems and methods for securing data in motion

A secure data parser is provided that may be integrated into any suitable system for securely storing data in and communicating data with cloud computing resources. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security.

Systems and methods for securing data in the cloud

System, method, signal, operating model, and computer program for electronic messaging. Systems and method for providing security for communication of electronic messages, interactive sessions, software downloads, software upgrades, and other content from a source to a receiving device as well as signals used for such communications. Systems, methods, signals, device architectures, data formats, and computer program structures for providing authentication, integrity, confidentiality, non-repudiation, replay protection, and other security properties while minimizing the network bandwidth, computational resources, and manual user interactions required to install, enable, deploy and utilize these security properties. System, device, method, computer program, and computer program product for searching and selecting data and control elements in message procedural/data sets for automatic and complete portrayal of message to maintain message intent. System, device, method, computer program, and computer program product for adapting content for sensory and physically challenged persons using embedded semantic elements in a procedurally based message file.

Secure certificate and system and method for issuing and using same

An intermediary provides certificate information by receiving from a first other entity authenticated certificate information, processing at least a portion of the authenticated certificate information to obtain deduced information, if the deduced information is consistent with the authenticated certificate information, having a witness construct authenticated deduced information by authenticating at least one of: the deduced information, the deduced information together with date information, and the deduced information together with additional information, and by providing the authenticated deduced information. The date information may be at least one of: the current date and date information of the authenticated certificate information. The witness may do the processing. The witness may be the intermediary. The authenticated certificate information and/or the authenticated deduced information may include a digital signature, which may be relative to a verification key that is part of an issued certificate and/or may be computed by applying a one-way function to one or more secret values or by iterating a one-way function. The digital signature may keep the witness accountable for the fact that the authenticated deduced information is consistent with the authenticated certificate information.
