Abstract: Techniques are described for generating and presenting a digital document for a transfer. A check service may generate the digital document based on provided check data. The digital document may be stored on a user device and presented to a recipient, for example through the display of the user device. The digital document may also be provided to the recipient in an email or other type of communication. The check service may generate a digital watermark to include on the digital document. The watermark may be unique to the particular document, and may be algorithmically generated based on data that is associated with the particular document, such as a serial identifier, a transaction identifier, an amount, a user identifier of the sender, etc. The digital watermark may be regenerated when the recipient presents the document for payment, to confirm document validity.

Abstract: A computer system and method having a user interface including a touch-sensitive display screen. The system and method enables entry of a password which includes displaying a first array of a plurality of images on the touch-sensitive display prompting a user to select with a finger one of the plurality of images displayed. Subsequently at least another array of a plurality of images successive to the first array is displayed on the touch sensitive display prompting a user to select with a finger one of the plurality of images displayed in the another array of images. A computer processor then determines if a user selected a predetermined image from the first array of the plurality of images and a predetermined image from each at least another array of plurality of images displayed after the first array. If determined, the user is permitted access to an application executable on the computer system.
