Description

  According to the present invention, in order to guarantee the erasure of data stored in a personal computer or hard disk requested for disposal, the data erasure situation in the hard disk and the data erasure when physically destroying a hard disk in which data can not be erased, The present invention relates to a disposal personal computer data management system that manages hard disc disposal information.

  When disposing a personal computer used in a company, it is necessary to completely erase trade secret information such as customer information and technical information. Generally, when saying "delete data", the data is discarded to the "trash" and the "delete" operation is performed, or the data is deleted using the "empty trash" command. Furthermore, use the software for initialization (format), use the recovery CD attached to the personal computer, and return to the factory shipment condition, etc., and return the data to the data non-input state before using the personal computer, and so on. to erase.

  However, even if such an operation is performed, the file management information of the data recorded in the hard disk may be changed, and the data may actually be invisible. Even though these data seem to be erased at first glance, the original data remains even if the process to call those data can not be performed under the OS installed on the personal computer. It is in the state of. Therefore, if special software for data recovery is used, it may be possible to read these data and it is possible to restore them. In such a case, the HD must be physically destroyed and rendered unusable if it is desired to completely prevent data leaks in the hard disk.

  Usually, it is difficult for companies using personal computers to dispose of themselves, so they will ask a disposal company. However, for PCs that have been requested to be disposed of, all data in the hard disk must be erased and then recycled as second-hand PCs, or the hard disk can be sold as second-hand even though the PC itself can not withstand recycling due to contamination or damage. There is a market where there are many cases, and there are management circumstances where the disposal company can not but compete for price by setting disposal fees in anticipation of income from there. In addition, in order to physically destroy the hard disks of all PCs requested for disposal, it is necessary to take out the hard disks from all the PCs, and since the standards of the PCs are diverse, manpower must be used. Well, there is a cost. Furthermore, even after physically destroying a hard disk, proper disposal as industrial waste is required, which also causes cost. Therefore, there is a possibility that the data deletion in the hard disk will be incomplete and it may be distributed to the second-hand market.

  On the other hand, companies that have requested the disposal of personal computers will only confirm that the possibility of data leakage has disappeared using only the data deletion certificate or personal computer disposal certificate issued from the disposal company. The status of the disposal can not be confirmed, and even if a certificate is issued, there is a possibility that a PC or a hard disk main unit may not be sufficiently erased in the hard disk data. If such a trade secret leaks out, it will suffer serious damage to credit and business.

  A method of managing deletion of data of one or more information devices managed by a client in order to solve such a problem, which is a step of acquiring a list including device identification information for identifying the information devices, and a list And a step of receiving an instruction to delete data of the information device included in the and an instruction to delete data of the information device included in the list including list identification information for identifying the list in response to receiving the instruction to delete the data Notifying the vendor of the instruction information indicating that, managing the status corresponding to the acquired list and deleting data of the information device included in the list, list identification information, and the list And displaying on the display unit of the client terminal in association with the status corresponding to That (Patent Document 1).
