Wireless communication method and apparatus for generating, watermarking and securely transmitting content

A wireless transmit/receive unit (WTRU) comprising:

• a content generation unit for generating content and appending a header to the content;
• a watermark incorporation unit for determining the type of watermark that should be applied to the content based on user input, hardware signature, radio frequency environment, type of wireless communication session and protocol, and perceived threat at the time of transmission of the content and for incorporating the watermark in the content;
• and
• a communication subsystem for transmitting the watermark incorporated content, whereby transmission of the content is secured by the incorporated watermark, and identity (ID) and location information are added to the header while the content is in transit to determine the trail of the content.
