For various reasons, people may deny having performed certain acts, for example because these acts violate instructions, security policies or even laws. However, they could also deny having received a notification, for example because they have forgotten an appointment or deadline. In the area of information security, the binding nature is therefore often pointed out, a characteristic which is used to ensure that acts that actions taken cannot be denied without justification. In this context, the term "non-repudiation" is used.

In communications, an additional distinction is made as to whether a communications subscriber denies the receipt of messages (repudiation of receipt) or the dispatch of messages (repudiation of origin). Denying the receipt of messages may be relevant, amongst other things, for financial transactions, e.g. if someone denies having received an invoice within the time stipulated. A communications subscriber can also repudiate transmission of a message, e.g. deny having sent an order. Having sent or received a message can be denied in the case of post just as with fax or e-mail.

Example:

• An electronic order is placed for an urgently needed spare part. After a week, a complaint about non-delivery of the part was lodged. In the meantime, high costs are incurred by the loss of production. The supplier denies ever having received such an order.
