摘要： A method of encoding input data in an encoder to generate corresponding encoded data includes splitting and/or transforming the input data into data chunks, analyzing symbols present in the input data and compressing the symbols as a function of occurrence of the symbols in the data chunks; generating code tables, frequency tables, and/or length of code word tables for the symbols present in the data chunks; computing sets of indices relating the symbols in each data chunk and/or the compressed symbols to entries in the code tables, the frequency tables, and/or the length of code word tables; and assembling the sets of indices, together with the frequency tables, the code tables, and/or information indicative of such tables, for generating the encoded data. An encoder that utilizes the method, together with a corresponding decoder, wherein the encoder and the decoder in combination form a codec.

摘要： An encoder includes data processing hardware which is operable: to divide input data into a plurality of blocks or packets; to apply a plurality of transformations to content of the blocks or packets to generate corresponding transformed data; to check a quality of representation of the transformed data prior to application of the transformations to determine whether or not the quality of representation of the transformed data satisfies one or more quality criteria; if the quality of representation of the transformed data does not satisfy the one or more quality criteria, to sub-divide and/or to combine the one or more blocks or packets further and repeating the transformation step; and if the quality of representation of the transformed data satisfies the one or more quality criteria, to output the transformed data to provide encoded output data representative of the input data to be encoded.

摘要： There is provided an entropy modifier which is operable to encode, alternatively decode, a stream of input data bits having a first entropy for generating corresponding entropy-modified output data having a second entropy, wherein the entropy modifier is operable to process the stream of input data bits to handle groups of mutually similar bits and the value of the first bit, and one or more maximum run lengths of the groups of mutually similar bits. Optionally, the entropy modifier is operable to control one or more maximum run lengths of the groups of mutually similar bits by using at least one escape code.

摘要： A system for providing protected data storage in a data memory of a computing device has an encoder and a decoder. The encoder encrypts unencrypted data using encryption information to generate encrypted data, and stores the encrypted data and the encryption information in an allocated portion of the data memory. The decoder accesses the encrypted data and the encryption information from the allocated portion of the data memory, and decrypts the encrypted data using the encryption information to re-generate the unencrypted data. Each time the unencrypted data is read from the allocated portion of the data memory or the unencrypted data is to be written to the allocated portion of the data memory, the encoder re-encrypts the unencrypted data using newer encryption information to generate newer encrypted data, and replaces previous encrypted data and previous encryption information with the newer encrypted data and the newer encryption information, respectively, in the allocated portion of the data memory. The encoder and the decoder are integrated, so as to operate in a single thread of execution.

the party is provided with an encryption key wallet and one or more encryption keys of the encryption key wallet are identifiable using at least one reference code.
The encryption key wallet is opened for accessing an encryption key via its reference code, for encrypting data to generate corresponding encrypted data and/or for decrypting encrypted data to generate corresponding decrypted data, wherein the encryption key is reproducibly generated by the encryption key wallet.
When the encryption system enables exchange of encrypted data via the encryption system between two or more parties
the two or more parties are provided with the encryption key wallet;
data exchanged between the parties are encrypted using one or more encryption keys obtained from the encryption key wallet; and
the encryption key wallet is opened for use when encrypting and/or decrypting the data exchanged between the parties.-
