Abstract
Tokens/keys are produced for wireless communications. These tokens/keys are used for watermarks signature insertion encryption and other uses. In one embodiment contextual information is used to generate tokens/keys. The tokens/keys may be derived directly from the contextual information. The contextual information may be used in conjunction with other information to derive the tokens/keys. Tokens/keys may be exchanged between transmit/receive units. The exchange of these tokens/keys may be encrypted.

Claim
1. A method comprising:
producing wireless transmit/receive unit (WTRU) specific information based on information specific to a user of the WTRU and context information relating to the user, wherein the context information relating to the user includes at least one of the following: rules and modes of user controlled WTRU operation, Internet preferences of the user, or web favorites of the user;
converting the WTRU specific information into an N-bit vector of fixed length;
producing a user specific token/key using the N-bit vector based on a specific application for the tokens/keys;
using the produced token/key to produce a watermark, signature or encryption code; and
inserting the watermark, signature or encryption code into a signal to be transmitted wirelessly.', 'producing wireless transmit/receive unit (WTRU) specific information based on information specific to a user of the WTRU and context information relating to the user, wherein the context information relating to the user includes at least one of the following: rules and modes of user controlled WTRU operation, Internet preferences of the user, or web favorites of the user;', 'converting the WTRU specific information into an N-bit vector of fixed length;', 'producing a user specific token/key using the N-bit vector based on a specific application for the tokens/keys;', 'using the produced token/key to produce a watermark, signature or encryption code; and', 'inserting the watermark, signature or encryption code into a signal to be transmitted wirelessly.
2. The method of claim 1 wherein the information specific to the user of the WTRU is selected from the group consisting of a code word, a password, a personal identification number, a biometric reading of the user, radio frequency (RF) tags, or a credit/debit/smart card.
3. The method of claim 1 wherein the produced token is used to authenticate the WTRU.
4. A method comprising:
providing a first token/key for use in producing a watermark, signature or encryption code, wherein the first token/key is derived from an N-bit vector based on a specific application for the tokens/keys, and wherein said N-Bit vector is derived from a wireless transmit/receive unit (WTRU) user specific information and information relating to a context of the user, wherein the context information relating to the user includes at least one of the following: rules, and modes of user controlled WTRU operation, Internet preferences of the user, or web favorites of the user;
based on the first token/key, producing a second token/key, the production of the second token/key is either a function of or derived from the first token/key or controlled by the first token/key; and
generating a watermark from the second token/key and inserting the watermark into a wireless communication signal.', 'providing a first token/key for use in producing a watermark, signature or encryption code, wherein the first token/key is derived from an N-bit vector based on a specific application for the tokens/keys, and wherein said N-Bit vector is derived from a wireless transmit/receive unit (WTRU) user specific information and information relating to a context of the user, wherein the context information relating to the user includes at least one of the following: rules, and modes of user controlled WTRU operation, Internet preferences of the user, or web favorites of the user;', 'based on the first token/key, producing a second token/key, the production of the second token/key is either a function of or derived from the first token/key or controlled by the first token/key; and', 'generating a watermark from the second token/key and inserting the watermark into a wireless communication signal.
5. A wireless transmit/receive unit (WTRU) comprising:
a WTRU specific token/key generation device configured to produce a token/key associated with a specific application for the tokens/key, said token/key derived from an N-bit vector that is derived from information associated with a user of the WTRU and context information relating to the user of the WTRU, wherein the context information relating to the user includes at least one of the following: rules and modes of user controlled WTRU operation, Internet preferences of the user, or web favorites of the user;
a watermark/signature/encryption code generation device having an input configured to receive the token/key and produce a watermark/signature/encryption code; and
a watermark insertion/signature insertion/encryption device having an input configured to receive a communication signal and an output configured to produce a watermark inserted/signature inserted/encrypted signal for wireless transmission.', 'a WTRU specific token/key generation device configured to produce a token/key associated with a specific application for the tokens/key, said token/key derived from an N-bit vector that is derived from information associated with a user of the WTRU and context information relating to the user of the WTRU, wherein the context information relating to the user includes at least one of the following: rules and modes of user controlled WTRU operation, Internet preferences of the user, or web favorites of the user;', 'a watermark/signature/encryption code generation device having an input configured to receive the token/key and produce a watermark/signature/encryption code; and', 'a watermark insertion/signature insertion/encryption device having an input configured to receive a communication signal and an output configured to produce a watermark inserted/signature inserted/encrypted signal for wireless transmission.
6. The WTRU of claim 5 further comprising:
a token/key recovery device for recovering a token/key from received wireless transmissions.', 'a token/key recovery device for recovering a token/key from received wireless transmissions.']
