A multimedia data construct called a tag (FIG. 5) may be stored and transferred. A user can use multimedia content, to create content portion of a tag (502). The multimedia file is then incorporated into the tag or it can be referenced by a pointer in the tag (530). The multimedia file is artistic expression of the user and the tag uniquely associates the user's identity with the multimedia file by prohibiting alteration of the content after the user completes its creation. The tag includes at least one dynamic indicator that may be changed based on one or more predefined rules upon transmission. The tag may include an ID, that may be based on subscriber information. Encryption techniques may be employed to protect privacy concerns so that such subscriber information is not freely available.
