Abstract

A computer readable medium storing a program causing a computer to execute a process for information processing, the process includes: receiving a first characteristic value calculated on the basis of first document information for use in detecting whether the first document information is tampered with or not; receiving a second characteristic value calculated on the basis of second document information for use in detecting whether the second document information is tampered with or not; and calculating a third characteristic value for use in detecting whether third document information is tampered with or not on the basis of the first characteristic value, the second characteristic value and the third document information related to integration of the first document information and the second document information.

Claims

1. A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:

receiving a first characteristic value calculated on the basis of first document information for use in detecting whether tampering with the first document information has occurred;

receiving a second characteristic value calculated on the basis of second document information for use in detecting whether tampering with the second document information has occurred;

calculating a third characteristic value for use in detecting whether tampering with third document information has occurred on the basis of the first characteristic value, the second characteristic value and the third document information related to integration of the first document information and the second document information; and

generating the third document information, indicating integration of the first document information and the second document information when an instruction to integrate the first document information and the second document information is received,

wherein the third document information is generated to include first user information for identifying a first user that initiated the integration of the first document information and the second document information, and

wherein the third document information comprises;

an execution request document created in response to the first user initiating the integration of the first document information and the second document information; and

an execution confirmation document created in response to a second user confirming the integration of the first document information and the second document information initiated by the first user.

2. The non-transitory computer readable medium according to claim 1,

wherein the third document information is generated to include an indication that a subject of the second document information is a subject of the first document information.

3. The non-transitory computer readable medium according to claim 1, the process further comprising:

determining whether a subject of the first document information is identical to a subject of the second document information on the basis of a determination criterion set in advance,

wherein, when the subject of the first document information and the subject of the second document information are determined to be identical, the first document information and the second document information are integrated.

4. The non-transitory computer readable medium according to claim 3,

wherein the first document information and second document information are related to a patient in a medical field, and

wherein the determining whether the patient as the subject of the first document information is identical to a patient as the subject of the second document information is conducted by using at least one of a name, birth date, physical information, information for biometric identification of the patient as the determination criterion set in advance.

5. The non-transitory computer readable medium of claim 1, wherein the process further comprises changing a first patient ID associated with the first document information to a second patient ID associated with the second document information upon generating the third document information.

6. An information processing apparatus comprising:

a computer processor configured to;

receive a first characteristic value calculated on the basis of first document information for use in detecting whether tampering with the first document information has occurred;

receive a second characteristic value calculated on the basis of second document information for use in detecting whether tampering with the second document information has occurred;

calculate a third characteristic value for use in detecting whether tampering with third document information has occurred on the basis of the first characteristic value, the second characteristic value and the third document information related to integration of the first document information and the second document information; and

generate the third document information which includes a message indicating integration of the first document information and the second document information when an instruction to integrate the first document information and the second document information is received,

wherein the third document information is generated to include first user information for identifying a first user that initiated the integration of the first document information and the second document information, and

wherein the third document information comprises;

an execution request document created in response to the first user initiating integration of the first document information and the second document information; and

an execution confirmation document created in response to a second user confirming the integration of the first document information and the second document information initiated by the first user.

7. An information processing method comprising:

receiving, at a processor, a first characteristic value calculated on the basis of first document information for use in detecting whether tampering with the first document information has occurred;

receiving a second characteristic value calculated on the basis of second document information for use in detecting whether tampering with the second document information has occurred;

calculating a third characteristic value for use in detecting whether tampering with third document information has occurred on the basis of the first characteristic value, the second characteristic value and the third document information related to integration of the first document information and the second document information; and

generating the third document information which includes a message indicating integration of the first document information and the second document information when an instruction to integrate the first document information and the second document information is received,

wherein the third document information is generated to include first user information for identifying a first user that initiated the integration of the first document information and the second document information, and

wherein the third document information comprises;

an execution request document created in response to the first user initiating the integration of the first document information and the second document information; and

an execution confirmation document created in response to a second user confirming the integration of the first document information and the second document information initiated by the first user.

8. A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:

receiving a first characteristic value calculated on the basis of first document information for use in detecting whether tampering with the first document information has occurred;

receiving a second characteristic value calculated on the basis of second document information for use in detecting whether tampering with the second document information has occurred;

generating, when it upon determining that a subject of the first document information is identical to a subject of the second document information on the basis of a determination criterion set in advance, third document information which comprises an execution request document indicating integration of the first document information and the second document information;

generating, upon determining that the subject of the first document information is not identical to the subject of the second document information on the basis of the determination criterion set in advance and upon receipt of an instruction from a first user to integrate the first document information and the second document information, the third document information comprising;

the execution request document indicating integration of the first document information and the second document information;

a first user information for identifying the first user that initiated the integration of the first document information and the second document information; and

an execution confirmation document created in response to a second user confirming the integration of the first document information and the second document information initiated by the first user; and

calculating a third characteristic value for use in detecting whether tampering with the third document information has occurred on the basis of the first characteristic value, the second characteristic value, and the third document information.
