Description
Technical field
The utility model relates to technical field of memory, particularly relates to a kind of cloud storage security lock.
Background technology
Cloud storage is in cloud computing (cloud computing) conceptive extension and the new concept of development out one, refer to by functions such as cluster application, grid or distributed file systems, various dissimilar memory device a large amount of in network is gathered collaborative work by application software, a system of data storage and Operational Visit function is externally provided jointly.When the core of cloud computing system computing and process is the store and management of mass data, just need in cloud computing system to configure a large amount of memory devices, so cloud computing system is just transformed into a cloud storage system, so the cloud computing system that cloud storage is is core with data store and management.In simple terms, cloud stores is exactly the emerging scheme of one be put into by storage resources for people's access on cloud.User can at any time, Anywhere, to be connected on cloud access data easily through any web-enabled device.
According to relevant statistics display, the user data new increment of cloud stores service business every day of a domestic line has reached in units of PB, has visible every day hundreds of millions of users to upload in oneself cloud memory space and downloads various file.In such a case, get rid of outside network bandwidth consumption, also expose the following hidden danger under cloud storage simultaneously.
One is copyright problem.About copyright problem has appeared in domestic net dish service on a large scale, some individuals or group can by the client upload that stored by cloud based on the file of video display music in net dishes, then the mode by sharing provides download in circle, a large amount of Video Musics of copyright that has is propagated by this special pirate mode, and this circulation way temporarily belongs to the blank of supervision, part cloud storage provider starts to limit the scope linking and share under the pressure of copyright unit, strengthens the filtration of file.But the piracy that these means fundamentally can not solve user's upload file in cloud storage is propagated.
Two is privacy concerns.A lot of mobile platform user is had to like oneself being stored by cloud with the photo of mobile phone or dull and stereotyped shooting and video at any time uploading in net dish fast, even immediately, photo can be fetched in strange land very efficiently like this by WEB or pc client, but the service end that each photo uploaded or alternative document are all likely clouds to be stored expressly is preserved, according to the personnel's introduction participating in the exploitation of certain cloud stored items, consider to realize encrypted private key from O&M cost unrealistic, keeper can directly check and delete the file that user uploads from the platform of service end, classified papers or user's privacy of user is no lack of in these files, present stage, large-scale service end was all carry out the professional personal integrity of Constraints Management personnel by setting up strict system, but people is vulnerable, once the personal integrity of people is abandoned, in its scope of authority, all there is serious potential safety hazard in visual content.
SPI FLASH memory technology adopts SPI protocol, SPI is a kind of high speed, full duplex, synchronous communication bus, and on the pin of chip, only take four lines save chip pin, effectively save PCB design arrangement space, reduce product size, the manufacturing cost of SPI FLASH lower than NAND FLASH, thus effectively saves product cost.
Existing movable storage device only has single data storage function, data are preserved with form expressly, there is great security risk, and traditional cloud storage security lock function single face form is single, limit and use with the pairing of the mobile terminal device such as mobile phone, panel computer, product surcharge is low.
