IPC: B41J2/325
Filed: 1982-11-30
Abstract: PURPOSE:To prevent a recording information printing traces from being read by a third person even if the ink of an ink layer is missed due to transfer printing, by forming the titled ink film from an ink layer comprising ink which is a solid phase at a room temp. but reversibly converted to a liquid phase by heating and a base film layer having the same color as said ink layer and containing a transparent material or coated therewith. CONSTITUTION:An ink film 1 consists of an ink layer 7 and a base film layer 8 and the ink layer 7 is formed of ink which is a solid phase at a room temp. and reversibly converted to a liquid phase by heating. In addition, the base film layer 8 has the same color to that of said ink and contains a transparent material. By using thus formed ink film 1, even if the ink of the ink layer 7 is missed in a character shape and transferred in recording, the residual ink part and the base film layer 8 are not discriminated because they have the same color. Therefore, a white omission phenomenon is not generated and recording information is not read by a third person. As a result, a special erasing means is unnecessary.

Abstract: PROBLEM TO BE SOLVED: To stop reading of secret information of a processor itself by immediately stopping execution of an execution program when the execution program is detected to be forged before the specified execution program is run. SOLUTION: A message digest processing is executed by branching a system into reset entry addresses of incorporated RUM/PROM after the system is reset. In this case, a message digest MD' is assigned to data byte obtained at the end of each processing. A message digest MD at editing is collated with the message digest MD' before which the message digest processing is executed whenever the execution program is run.
