Abstract: Very strong, complex, unforgettable passwords unique to each web site are created for a user's Web site authentication by altering all or part of the web site address using, in a preferred embodiment, a predetermined encoding dictionary with more a single code for each entry. The entries in this preferred embodiment are single characters including characters used for words, punctuation, symbols and numerals; each single entry character appears more than once in the dictionary. The codes are of various character lengths and can be comprised of the same characters used in the entries. In an embodiment for pass-protecting files, the string of characters altered by encoding can be a private word or group of words. In another embodiment the password created by encoding is pseudo-randomly scrambled by using a seed unique to the user in order to create the password actually used.

In a Web site authentication embodiment as well as for embodiments not used for Web site authentication, including pass-protecting files, the string of characters altered by encoding can be a private word or group of words. In another embodiment the password created by encoding is pseudo-randomly scrambled by using a seed unique to the user in order to create the password actually used.

Abstract: Text compression and encryption is achieved by using a predetermined dictionary not unique to the encoded text to substitute codes for words and phrases thereby obviating transmission of the dictionary along with transmitted encoded text. The codes of the dictionary are made of one or more text characters such that the message, once encoded, continues to be a legitimate text message and can travel through any data transport medium through which a conventional unencoded text message can travel. Non-word characters delimit codes and unencoded words in an encoded message. Advantages include message filtering and maintaining message threads of short messages, including SMS.

Abstract: Text is encoded using a predetermined dictionary not unique to the encoded text to substitute codes for words and phrases thereby obviating transmission of the dictionary along with transmitted encoded text. The codes of the dictionary are made of one or more text characters such that the message, once encoded, continues to be a legitimate text message and can travel through any data transport medium through which a conventional text message can travel. Non-word characters delimit codes and unencoded words in an encoded message. Any phrase that can be confused with a code is flagged to indicate that it is not a code.
