1. A method comprising: receiving, from a device of a user, a request to transmit a multimedia file; automatically generating a content descriptor based on an analysis of the multimedia file using an analysis parameter, wherein the content descriptor includes a reputation rating of a publisher of the multimedia file, wherein the reputation rating is determined based on combining a set of scores associated with the publisher, and wherein each score of the set of scores is determined based on deviation of a particular content descriptor for a particular multimedia file from a file descriptor for the particular multimedia file; determining whether the content descriptor satisfies filter criteria of a profile associated with the user, wherein the filter criteria includes a preferred reputation rating, wherein the content descriptor satisfies the filter criteria when the reputation rating of the content descriptor matches the preferred reputation rating, wherein the reputation rating is a positive rating when a combination of the set of scores produces a combined positive score, wherein the reputation rating is a negative reputation rating when a combination of the set of scores produces a combined negative score, wherein the preferred reputation rating is one of the positive rating and the negative rating, wherein each score is a positive score when the deviation is less than an allowable variance, and wherein each score is a negative score when the deviation exceeds the allowable variance; rejecting the request to transmit the multimedia file in response to the content descriptor not satisfying the filter criteria of the profile; and transmitting the multimedia file along with the content descriptor in response to the content descriptor satisfying the filter criteria of the profile.
