Abstract: Content uploaded to a video distribution service is analyzed to determine if a portion matches part of any reference work. If a match is found, treatment of the uploaded content is determined based on stored rule data, and based on one or more factors. These factors can include, e.g., the length of the matching portion, the part of the reference work from which the matching portion was apparently copied, the confidence of the match, the popularity of the uploaded content (or of the reference work), the geography from which the content was uploaded (or the geography to which it is to be downloaded), etc. Further determinations may be made by human evaluators (including crowd-source approaches). A great variety of other features and arrangements are also detailed.

Abstract: A method of and system for authorizing purchases made over a computer network is provided. In accordance with the present invention, a consumer electronically transmits an ATM card number over the network to an on-line merchant from which the consumer desires to make a purchase. The on-line merchant then electronically forwards the ATM card number to a third party contractor, such as a bank, that will oversee and authorize the transaction. The third party contractor subsequently determines an authentication token type associated with the card and electronically prompts the consumer for the appropriate type of authentication token, such as a PIN or biometric signature or the like. The consumer then inputs and electronically transmits the authentication token over the network to the third party contractor, bypassing the on-line merchant.

Abstract: The systems and methods of the invention provide a technique for authenticating a finance related transaction. The method may include providing a token which contains a token counter, the token counter periodically advancing to generate a changing token value, the token counter being synchronized to a base counter that generates an authenticating value; transforming the token value into a token output sequence using logic; and outputting at least part of the token output sequence to an authenticating authority, the authenticating authority having access to the authenticating value.
