Abstract: A secure authentication system, computer program recording medium and method enable secure transaction with authentication to eradicate fraud. A customer is authenticated via a customer application executed on a communication device. A customer-paced communication session is enabled between the customer application and a transaction system via a network connection. A customer continuity factor is monitored in maintaining the communication session. In response to receiving a customer request via the customer application, a level of trust in current authentication of the customer is determined based on the user continuity factor. In response to the level of trust being below a trust threshold, the customer is directed via the customer application to provide a customer request comprising a customer-supplied image having a specified contextual element. The communication session is re-authenticated to process the user input by the transaction system based on verification of the received user-supplied image.
