Abstract
An information processing apparatus includes circuitry. The circuitry transmits document data in response to a request signal transmitted from an information processing terminal and requesting output of the document data. Based on an information signal transmitted from the information processing terminal and indicating information that is not described in a document indicated by the document data, the circuitry generates latent-image data as a latent image including the information signal and the document data. The circuitry outputs the latent-image data and the document data.
Claims7
An information processing apparatus, comprising:
- a processor configured to:
- receive document data from a data server in response to a request signal transmitted from an information processing terminal, the request signal requesting output of the document data;
- receive, based on an information signal transmitted from the information processing terminal, the information signal indicating information that is not described in a document indicated by the document data;
- generate tamper-proof latent-image data which includes both the document data and the information signal;
- create a composite image by combining the document data which is in a human readable form with tamper-proof latent-image data that is invisible or hardly visible to a human;
- and
- output the composite image which was created.
