PURPOSE:To attain a security check system to protect a data base from the outside by checking whether an operation is possible or not in terms of relation between an operator and a processing function and changing the check contents according to the importance of secrecy of the processing function. CONSTITUTION:An operator/processing function memory means 10 stores information 40 on the operator names, passwords, security levels, process names, etc. in a memory part 30 of a computer system in such a style as shown in figure. An operation possibility decision/check means 20 receives the name of an operator, a password and a process name or the codes that can specify those said elements from the operator and compares them with the information 40 stored in the part 30. A processable state is decided only when coincidence is obtained between the received password and the one stored in the part 30 as long as the security levels are set under the state excluding a specific one (space or 0). Thus the corresponding operator can perform a processing operation. |
