Embodiment
In order more to be expressly understood above-mentioned purpose of the present invention, feature and advantage, the present invention is further described in detail below in conjunction with the drawings and specific embodiments.
Set forth a lot of details in the following description so that fully understand the present invention, still, the present invention can also adopt other to be different from other modes described here and implement, and therefore, the present invention is not limited to the restriction of following public specific embodiment.
Fig. 1 is the flow chart of data guard method according to an embodiment of the invention.
As shown in Figure 1, the invention provides a kind of data guard method, can comprise: step 102 is provided with the password corresponding to keyword; Whether step 104 contains keyword in the data query, when containing keyword in the data, access to your password data are carried out the encryption and decryption processing.By this technical scheme,, can select whether this to be encrypted, and how carry out encryption and decryption at different pieces of information by inquiry to keyword.
In technique scheme, in step 102, have when a plurality of at keyword, for a plurality of keywords are provided with priority orders; In step 104, when in data, containing a plurality of keyword,, select at least one password in the corresponding respectively a plurality of passwords of a plurality of keywords that data are carried out encryption and decryption and handle according to the priority orders of a plurality of keywords.By this technical scheme, can avoid the encryption and decryption of data is become too loaded down with trivial details, influenced user's checking to data.
In technique scheme, can also comprise: step 106, input password with before checking data the prompting user, be the keyword corresponding that comprises in the user prompt data with password.By this technical scheme, can guarantee that the user checks data easily.
In technique scheme, in step 104, regularly whether contain described keyword in the data query, or whether contain keyword in the data query during editing data.
By above technical scheme, can realize a kind of data guard method, by keyword and password are set, and in data search key, whether need encrypt, and use which password to carry out encryption and decryption if can judge each data automatically.
Fig. 2 is the block diagram of data protecting device according to an embodiment of the invention.
As shown in Figure 2, the present invention also provides a kind of data protecting device 200, can comprise: module 202 is set, the password corresponding to keyword is set; Whether encryption and decryption module 204 contains keyword in the data query, when containing keyword in the data, access to your password data are carried out the encryption and decryption processing.By this technical scheme,, can select whether this to be encrypted, and how carry out encryption and decryption at different pieces of information by inquiry to keyword.
In technique scheme, have when a plurality of at keyword, via being set, module 202 priority orders is set for a plurality of keywords; Via the priority orders of encryption and decryption module 204, select at least one password in the corresponding respectively a plurality of passwords of a plurality of keywords that data are carried out the encryption and decryption processing according to a plurality of keywords.By this technical scheme, can avoid the encryption and decryption of data is become too loaded down with trivial details, influenced user's checking to data.
