Abstract

An information processing apparatus comprises: a first storing unit which stores a job; a performing unit which performs the job stored in the first storing unit; an erasing unit which performs overwriting erasure of the job performed by the performing unit; a first recording unit which records first time information indicating a time when the performance of the job by the performing unit is completed, for each job; a second recording unit which records second time information indicating a time when the overwriting erasure of the job stored in the first storing unit is completed by the erasing unit; and a predicting unit which predicts, for each job, whether or not the erasure of the job was completed, based on the first time information and the second time information.

Claims

1. An information processing apparatus comprising:

a storing unit configured to store a job;

a performing unit configured to perform the job stored in the storing unit;

an erasing unit configured to perform overwriting erasure of the job performed by the performing unit;

a first recording unit configured to record first time information indicating a time when the performance of the job by the performing unit is completed, for each job;

a second recording unit configured to record second time information indicating a time when the overwriting erasure of the job stored in the storing unit is completed by the erasing unit; and

a predicting unit configured to predict, for each job, whether or not the erasure of the job was completed, based on the first time information and the second time information.

2. The information processing apparatus according to claim 1, wherein the predicting unit predicts that the erasure of the job was completed, in a case where the time indicated by the second time information is later than the time indicated by the first time information.

3. The information processing apparatus according to claim 1, further comprising a displaying unit configured to display a prediction result by the predicting unit for each job.

4. The information processing apparatus according to claim 1, wherein the first time information is stored in the storing unit.

5. The information processing apparatus according to claim 1, wherein the second time information is stored in the storing unit.

6. An information processing method comprising:

storing a job;

performing the stored job;

performing overwriting erasure of the performed job;

recording first time information indicating a time when the performance of the job is completed, for each job;

recording second time information indicating a time when the overwriting erasure of the stored job is completed; and

predicting, for each job, whether or not the erasure of the job was completed, based on the first time information and the second time information.

7. A non-transitory computer-readable medium which stores a computer program for causing a computer to perform an information processing method comprising:

storing a job;

performing the stored job;

performing overwriting erasure of the performed job;

recording first time information indicating a time when the performance of the job is completed, for each job;

recording second time information indicating a time when the overwriting erasure of the stored job is completed; and

predicting, for each job, whether or not the erasure of the job was completed, based on the first time information and the second time information.
