  • Patent number: 8613050
    Abstract: A license authentication system and method enabling authentication of an application to be installed in a client PC which is being incapable of communicating with the server which authenticates the application. A portable terminal performs license authentication of an application to be installed in a client PC in place of the server and gives the client PC a temporary right of use (step 1101 to step 1108). During the temporary use, the portable terminal performs regular license authentication in place of the client PC to obtain the regular right of use and gives the information relating to the right of use to the client PC (step 1109 to step 1116).

  • Patent number: 8181234
    Abstract: The security of an authentication system using a one-time password is increased, a shift from an authentication system using a fixed password is simplified, and a range of use is increased. An authentication system wherein a one-time password is synchronized with time, or an authentication system wherein a one-time password is synchronized with the number of online service authentication requests, is provided. When a one-time password client 9 downloads a one-time password for online service authentication from a one-time password server 2, current time information or a current value of the number of online service authentication requests is made to coincide between the client and server, and an online service authentication request is authenticated as long as the downloaded one-time password for online service authentication is valid. The one-time password may also be synchronized with service usage details contained in the online service authentication request.

  • Patent number: 8117167
    Abstract: There is provided a technique capable of executing a predetermined processing while continuing a database processing. Firstly, the database to be operated is switched from the main database to a duplicate database. The predetermined processing is executed to the main database which becomes the non-operation mode by the switching. Next, a database access request is distributed to the duplicate database which becomes the operation mode by the switching, thereby performing the database processing. Update information indicating the content of the update processing performed to the duplicate database is output. The output update information is reflected on the main data base for which the predetermined processing has been executed. After this, the database to be operated is switched from the duplicate database to the main database.

  • Publication number: 20110022811
    Abstract: To reduce the size of backup data, increase the backup speed, and solve a problem that the amount of unnecessary writing could undesirably increase in a restoration process, which would otherwise require physical disks with a capacity greater than the size of a virtual volume. On a backup server having mounted thereon a virtual volume that is the target to be backed up and restored, read/write access to only the blocks of data areas is performed by a device driver that filters I/O access to a device from a file system on the basis of the data mapping information of the virtual volume, whereby read/write access to unnecessary portions is avoided. Thus, it is possible to reduce the size of backup data, increase the backup speed, and prevent an increase in the amount of unnecessary writing to the virtual volume in a restoration process.

  • Patent number: 7809191
    Abstract: In order to increase the recognition rate of a shadow area contained in the image of an aerial photograph, a central control portion performs the processes of: comparing a shadow-produced angle with the angles of segments constituting the polygons generated by a polygon-generating portion to judge whether or not there are the segments coinciding with the shadow-produced angle, of the segments constituting the polygon; judging whether or not the ratio of the length of the segment constituting the shadow to the length of the segment constituting the feature coincides with a shadow-extended ratio; judging whether or not the color tone of the area surrounded by the segments constituting the shadow is darker than that of all the adjacent polygons; and identifying the area surrounded by the segments constituting the shadow as “shadow area.” The polygon of the identified shadow area is generated.

  • Publication number: 20100246975
    Abstract: For an image of an object for use in biometrics and the like, if the imaging object is still is detected with a simple configuration. From two pieces of image data that have been captured in time series, the absolute value of the difference in brightness of pixels in the identical position is calculated, and the number of pixels whose absolute values exceed the threshold value indicative of the limit of the brightness change is counted. The counted result is compared with the movement determination threshold value to determine if the imaging object is still.

  • Patent number: 7783430
    Abstract: A method and a system for evaluating results of differentiating genotype signals and noise signals when a DNA fragment containing a gene to be analyzed is amplified by PCR and detected by electrophoresis are provided. An outlier of genotyping results is detected based on the fact that, when using the same marker, the height ratio of a stutter peak to a true peak and the height ratio of a +A peak to a true peak are reproducible, and that a constant size value is obtained with the use of the same allele of the same marker. In addition, a waveform obtained in past processes with the use of the same marker or the same allele is obtained utilizing a database by focusing on reproducibility. Also, a database is extended so as to obtain improved evaluation ability in a manner such that appropriate waveform data from which an outlier is not obtained is additionally registered in a database.

  • Publication number: 20100185852
    Abstract: Encryption and decryption is achieved without the requirement for updating of the encryption key or re-encryption of an encrypted file when a shared encrypted file is generated, renamed or deleted. In response to a request to read or store a shared encrypted file, a filter driver in a client computer receives client authentication from a key management server and acquires a key list having pairs of UNC path names and encryption keys corresponding to shared encrypted folders allowed to be accessed from the key management server. The filter driver accesses a shared encrypted folder as a destination of the read or store request and performs decryption or encryption of the shared encrypted file by using an encryption key of the key list corresponding to a UNC path name concerned with the UNC path name to be accessed when the UNC path name concerned is present in the key list.
