Disclosed examples decrypt a first block of sequential blocks using a first decryption key generated based on a first hash of a second decryption key and bit stream data, the first decryption key associated with the first block of the sequential blocks to generate a first segment of a band entropy coded bit stream; generate a third decryption key for a second block of the sequential blocks based on a second hash of the first decryption key and data of the first block of the sequential blocks; decrypt the second block of the sequential blocks using the third decryption key associated with the second block of the sequential blocks to generate a second segment of the band entropy coded bit stream; and merge the first and second segments of the band entropy coded bit stream to generate a source data bit stream using a bit mask for demultiplexing.

Process efficient preprocessing for any encryption standard

A disclosed example separates a source data bit stream into at least a high bit stream and a low bit stream, the high bit stream and the low bit stream associated with an entropy band having an entropy designation indicating a level of entropy content, the entropy designation selected from an entropy designation range between a high entropy designation and a low entropy designation; entropy code the high bit stream and the low bit stream separately; create the at least two band entropy coded bit streams; generate a bit mask with a hash, the hash having inputs of at least a strong encryption key and selected data that is from the source data bit stream, the selected data not encrypted during any encryption process; merge the at least two band entropy coded bit streams into a resultant band entropy coded bit stream based on a sequence of at least one indexed value obtained from the bit mask; and at least one of store or share the resultant band entropy coded bit stream in a same file format as the source data bit stream.

A technique allows for transparently managing, suspending, restoring, sharing, limiting and migrating user sessions on a device without having access to user credentials. A user may automatically log in and out of each or all their online accounts instantaneously and, in doing so, the user may share sessions without sharing passwords across client devices as well as with other authenticated and authorized users. Sharing may be done in a secure manner with the initiating-user being able to restrict shared session rights, as well as being able to remove access to each of the shared sessions.

Automatic log-in and log-out of a session with session sharing

A pre-encryption process for symmetric encryption processes that inputs a bit stream into any existing or future encryption standard to increase encryption complexity with a disproportionate increase in processing time. The first encoding step is the two-stage generation of two strong keys based on a seed strong crypto key and known information from the Source Data bit stream. The second step is to split and encode the bit stream based on entropy levels. After entropy coding, the aligned bit streams are multiplexed in a cyclic fashion to generate one resulting bit stream. The third step is to slice the resulting bit stream into blocks, encrypting each block and adding each block to a coded output bit stream. Each new strong crypto key is derived from the previous crypto key and the previous pre-processed bit stream data. The decoding process is provided that is a simplified inverse of the encoding process.

A method and process for users to have secure access to multiple mobile, embedded or web based applications, is provided whereby each requires different authentication, and access to such applications is automated through the use of a single authenticating and authorizing software; the software thereby securely managing the individual authorizations and, in so doing, the authentication required by any individual application independent of the device used. To protect against any intrusion and manipulation while assuring that only legitimate user(s) that are properly authenticated have access to their applications the method secures the secret information required to access these applications and minimizes exposure to any sensitive information. Moreover, any secrets that protect information are themselves secured and made strong and the means of access is simplified and automated as much as possible while safeguarding security and confidentiality.

Secure automatic authorized access to any application through a third party

A future proof method and system for securely transferring digital data from a data owner to a data assignee through a third party involving securely registering the data owner possessing the digital data with the third party and securely predefining to the third party a trigger event associated with a data assignee, registering the data assignee with the third party, receiving encrypted digital data and an encrypted trigger event associated with the data assignee transmitted from the data owner to the third party, and securely transferring and releasing the digital data to the at least one data assignee by the third party upon validation by the third party of the occurrence of the trigger event in such a manner that digital data can be used by data assignee on data assignee system.
