Abstract: The instant invention relates to a system and method for ensuring and verifying the identity of all parties involved in an online marketplace transaction involving buyers, sellers, and third parties, such as a marketplace. Anonymous transactions are supported by the present invention. Verification is provided and insurance may be purchased in accordance with the instant invention guaranteeing that the parties are who they represent themselves to be and are capable of entering into the transaction, thereby facilitating completion of the online transaction.

Abstract: Using know methods a digital signature, such as a one-way hash, of a document is produced. A digital representation of a signature is associated with the digital signature. The digital representation may be, for example, a digitized picture of the signature. Both the digital signature and the digital representation of the signature are sent to a recipient. The recipient may then view the digital representation of the signature and provide visual confirmation of the authenticity of the signature. In addition, the digital representation of the signature may be electronically analyzed to determine a match. The digital representation of the signature may then be shown to the recipient when the electronic analysis indicates an authentically signed document so as to provide a visual assurance of integrity.

Abstract: A system for increasing the security of a computer system, while giving an individual user a large amount of flexibility and power. To give users the most power and flexibility, a standard object that has the capability to embed objects is used. To allow users even more flexibility, a standard object tracking mechanism is used that allow users to distribute multiple encrypted embedded objects to other individuals in a single encrypted object. By effecting compartmentalization of every object by label attributes and algorithm attributes, multi-level multimedia security is achieved.

By effecting compartmentalization of every object by label attributes and algorithm attributes, multi-level multimedia security is achieved. Label attributes are used to restrict access to objects based on location, group, or other criteria and may specify personal access. Access type, such as read-only, write-only, and print-only may be specified. Nested embedded objects may be accessed directly through selection from a header array.
