Method for clearing disk space

InactiveCN102333079APrevent data from being stolenPerfect data recovery and backupInput/output to record carriersTransmissionStorage efficiencyCloud storage
The invention provides a method for clearing disk space, and is suitable to clear the disk space of portable cloud storage. In a system comprising a portable cloud storage device, a host machine and a remote cloud storage server, the method comprises the following steps of identifying whether the file opened by a user is in a queue, wherein the queue is a filename queue used for saving the names of the files used by the user recently; if so, deleting the filename from the queue and executing the next step; if not, executing the next step; placing the filename in the end part of the queue; identifying whether the usage space of the currently used disk reaches or exceeds the preset clearing threshold, if so, executing the next step, if not, returning to finish; finding the file satisfying the preset condition according to the presetting rule, clearing one by one until the usage space of the currently used disk is smaller than a preset end clearing threshold. With the adoption of the method and the matched portable storage device and the remote cloud storage server, the local storage space can be effectively saved, the limited portable storage resource can be greatly utilized, and thus, the storage efficiency of the cloud storage can be increased.

One-way secure data transmission method based on a public key password

The invention discloses a one-way secure data transmission method based on a public key password, and belongs to the technical field of public key password systems and secure data transmission. The method comprises the steps that on the basis of public key encryption, a public key is preset in data acquisition equipment, a private key is preset in service main equipment, and after configuration ofthe data acquisition equipment and the service main equipment is completed, the data acquisition equipment is configured to a data acquisition point to start a data acquisition mode for data acquisition work; The service main equipment is networked with the data acquisition equipment at the data acquisition point within the maximum working time range of the data acquisition equipment, and the data acquisition equipment starts a data sending and receiving mode to upload the data to the service main equipment. According to the method, the risk caused by the fact that all encrypted data are encrypted by the same secret key only by using the AES fixed secret key is solved; The efficiency is improved; The risk of key exposure is effectively avoided; And a security mechanism of one-time encryption is adopted, so that the data and the encryption key of the sending host are securely stored and transmitted.
