Abstract:
Systems and methods safeguarding online chat privacy via Unicode keywords encoding that are likely to carry the intent of messages within a conversation between two or more parties. Input of a set of keywords is obtained in chronological order from a conversation between two or more parties for the computing of hash values based on a word's influence on subsequent words in the conversation, and generating a ranked order of the keywords from highest to lowest hash value. Further, the method of the present invention includes generating a Unicode cipher table at the first chat device by obtaining an encryption key from the homomorphic key server to encrypt the Unicode cipher table comprises a homomorphic operation on a first table key in combination with a first chat device key and a second chat device key.

Claim (Index 8):
A system useful in secure online communication, wherein hash values that are likely to carry the intent of a conversation are used as factors in encoding of conversation, the system comprising:\n a homomorphic key server; a chat server; a first chat device having a chat memory; a second chat device registered at the homomorphic key server for communicating with the first chat device; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for: generating a Unicode cipher table at the first chat device by obtaining an encryption key from the homomorphic key server to encrypt the Unicode cipher table; generating in the chat memory a hash value for the Unicode cipher table; erasing the hash value from the chat memory when the first chat device is disconnected from the chat server; initiating a chat message at the first chat device, wherein the first chat device encodes the chat message by using the Unicode cipher table with the hash value to determine an encoded message; storing the encoded message in a server memory of the chat server; receiving the Unicode cipher table at the second chat device, wherein the second chat device obtains the homomorphic key from the homomorphic key server for decrypting of the Unicode cipher table; and obtaining the encoded message from the chat server at the second chat device, wherein the second chat device decodes the encoded message by using the Unicode cipher table, and the hash value is not known to the second chat device.
