(1) The data input by the user in the online environment that is used to drive a transaction. The output of transaction. (2) In steganography, the data a sender wishes to remain confidential. This data can be text, still images, audio, video, or anything that can be represented as a bitstream. The communications to or input for an object (in the context of object-oriented programming terminology and concepts).

A security service by which evidence is maintained so that the sender and recipient of data cannot deny having participated in the communication. Referred to individually as nonrepudiation of origin and nonrepudiation of receipt. Assurance the sender of data is provided with proof of delivery and the recipient is provided with proof of the sender’s identity, so neither can later deny having processed the data.

A requesthandling mechanism that selects a method based on the type of target object. This allows the specification of one request that can result in invocation of different methods depending on the type of the target object. Most objectoriented languages support the selection of the appropriate method based on the class of the object (classical polymorphism). A few languages or systems support characteristics of the object, including values and userdefined defaults (generalized polymorphism). Having many forms. In the context of object-oriented programming terminology and concepts, the characteristic of an object to provide different behaviors based on the same message and methods owing to variances in external conditions.

In the context of object-oriented programming, the forwarding of a request by an object to another object or delegate. An object delegates if it does not have a method to handle the message. The notation that an object can issue a request to another object in response to a request. The first object therefore delegates the responsibility to the second object. Delegation can be used as an alternative to inheritance.

An implementation of an abstract data type. A definition of the data structures, methods, and interface of software objects. A template for the instantiation (creation) of software objects. In the context of object-oriented programming terminology and techniques, a collection of common methods from a set of objects that defines the behavior of those objects.
