1. A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising: determining a risk of information leakage by a user having indicated image processing; determining an increase in the risk of information leakage by at least one of an indication of a plan of the user to resign from an employer, an indication that the user is under suspicion by the employer and a comparison of a previous risk of information leakage, determined prior to determining the risk of information leakage; and controlling character recognition, the character recognition performing character recognition processing on an image subjected to the image processing, such that recognition accuracy of the character recognition processing is increased in response to the increase in the risk of information leakage, wherein the determining the increase in the risk of information leakage further includes determining, on a basis of statistics on log information of the image processing indicated by the user, a rate of deviation of a trend of image processing indicated by the user during a most recent period prior to a point of time of the determination from a trend of image processing indicated during a past normal period, and determining the risk of information leakage by the user on the basis of the determined rate of deviation.
