Information Processing Device and Method

1. An information processing device comprising: a memory; and a processor coupled to the memory, wherein the processor is configured to execute a process comprising: performing access restriction on access to a page on which information is posted from a terminal used by a subject, the access restriction being based on a keyword filtering scheme; determining whether geographical positions of the terminal used by the subject and a terminal used by an other user are in close proximity with each other, wherein the determining includes: acquiring terminal geographical position information from the terminal of the subject, acquiring terminal geographical position information from the terminal of the other user, and determining that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, when a distance between geographical position coordinates indicated by the acquired terminal geographical position information of the subject and the other user is within a predetermined value; receiving, when it is determined that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, a relaxation operation from the terminal used by the other user or the terminal used by the subject, wherein the relaxation operation performs one of: (i) relaxes the access restriction temporarily to a less restrictive level of access control, or (ii) temporarily stops the access restriction on access to the page; (i) relaxing the access restriction to the less restrictive level of access control, or (ii) stopping the access restriction, when the relaxation operation is received; acquiring a characteristic word from the page accessed by the terminal of the subject for which the access restriction is relaxed, the characteristic word having characteristics corresponding to access restriction determination characteristics of the page; transmitting the acquired characteristic word, which is displayed on the terminal used by the other user, to the terminal used by the other user; receiving a restore operation for restoring the access restriction from the terminal used by the other user; and restoring the access restriction to the previous level of access control, when the restore operation is received.

2. The information processing device according to claim 1 , wherein the determining includes determining that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, when it is determined that predetermined information has been directly transmitted and received between the terminals used by the subject and the other user.

3. The information processing device according to claim 1 , wherein the relaxation operation is not performed, when it is determined that the geographical positions of the terminals used by the subject and the other user are not in close proximity with each other.

4. An information processing method executed by a computer, the method comprising: performing access restriction on access to a page on which information is posted from a terminal used by a subject, the access restriction being based on a keyword filtering scheme; determining whether geographical positions of the terminal used by the subject and a terminal used by an other user are in close proximity with each other, wherein the determining includes: acquiring terminal geographical position information from the terminal of the subject, acquiring terminal geographical position information from the terminal of the other user, and determining that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, when a distance between geographical position coordinates indicated by the acquired terminal geographical position information of the subject and the other user is within a predetermined value; when it is determined that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, receiving a relaxation operation from the terminal used by the other user or the terminal used by the subject, wherein the relaxation operation performs one of: (i) relaxes the access restriction temporarily to a less restrictive level of access control, or (ii) temporarily stops the access restriction on access to the page; (i) relaxing the access restriction to the less restrictive level of access control, or (ii) stopping the access restriction, when the relaxation operation is received; acquiring a characteristic word from the page accessed by the terminal used by the subject for which the access restriction is relaxed, the characteristic word having characteristics corresponding to access restriction determination characteristics of the page; and transmitting the acquired characteristic word, which is displayed on the terminal used by the other user.

5. An information processing device comprising: a memory; and a processor coupled to the memory, wherein the processor is configured to execute a process comprising: performing access restriction on access to a page on which information is posted from a terminal used by a subject, the access restriction being based on a keyword filtering scheme; determining whether geographical positions of the terminal used by the subject and a terminal used by an other user are in close proximity with each other, wherein the determining includes: acquiring terminal geographical position information from the terminal of the subject, acquiring terminal geographical position information from the terminal of the other user, and determining that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, when a distance between geographical position coordinates indicated by the acquired terminal geographical position information of the subject and the other user is within a predetermined value; receiving, when it is determined that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, a relaxation operation from the terminal used by the other user or the terminal used by the subject, wherein the relaxation operation performs one of: (i) relaxes the access restriction temporarily to a less restrictive level of access control, or (ii) temporarily stops the access restriction on access to the page; (i) relaxing the access restriction to the less restrictive level of access control, or (ii) stopping the access restriction, when the relaxation operation is received; acquiring a characteristic word from the page accessed by the terminal of the subject for which the access restriction is relaxed, the characteristic word having characteristics corresponding to access restriction determination characteristics of the page; and transmitting the acquired characteristic word to the terminal used by the other user such that the characteristic word is displayed on the terminal used by the other user.

6. The information processing method of claim 4 , further comprising: receiving a restore operation for restoring the access restriction from the terminal of the other user; and restoring the access restriction to the previous level of access control, when the restore operation is received.

7. The information processing method of claim 4 , wherein the keyword filtering scheme is a white list filtering scheme or a black list filtering scheme.

8. The information processing device according to claim 5 , wherein the keyword filtering scheme is a white list filtering scheme or a black list filtering scheme.

9. The information processing method of claim 4 , further comprising: allowing, when it is determined that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, an input of the relaxation operation from the terminal used by the other user or the terminal used by the subject; and relaxing the access restriction to the less restrictive level of access control, or stopping the access restriction, according to the input of the relaxation operation.

10. The information processing device according to claim 5 , wherein the processor is further configured to: allow, when it is determined that the geographical positions of the terminals used by the subject and the other user are in close proximity with each other, an input of the relaxation operation from the terminal used by the other user or the terminal used by the subject; and relax the access restriction to the less restrictive level of access control, or stop the access restriction, according to the input of the relaxation operation.
