Abstract
The invention provides a method for encrypting a picture file and displaying the encrypted picture file. In the method, firstly a common picture file is encrypted by taking a password input by a user as a secret key; and when the user browses the encrypted picture file on a local computer or internet computer, the encrypted picture file is directly displayed by taking the password input by the user as the secret key without downloading a picture file or decrypting the encrypted picture file into the common picture file. The invention provides a method for conveniently and safely saving and browsing pictures for users.
Description
Technical field:
The present invention relates to a kind of method of encrypting picture file and showing the encryption picture file, more specifically say, relating to a kind of user can encrypt picture with password, and need not be decrypted into earlier under the situation of common picture file, browses the method for encrypting picture file with identical password.The user can be placed on the local computer or on the internet encrypting picture file, and use method provided by the invention, imports password and directly browses the encryption picture file, need not the download pictures file, also need not to be decrypted into earlier common picture file.The present invention provides a kind of picture of safe ready to preserve and browsing method to the user.
Background technology:
Along with the development of numeral science and technology, people often relate to a large amount of digital pictures files.Wherein a lot of pictures all need to encrypt, and know conveniently that again the people of password browses simultaneously.Present way is that the digital pictures file is encrypted, and is decrypted into common picture file when needing again and browses.Be placed on the encryption digital pictures file on the internet, also need to download to earlier local computer, be decrypted into common picture file again and just can browse.This method is cumbersome, and is also enough dangerous.
In present stage, the good method of neither one realizes the above-mentioned problem of mentioning.
Summary of the invention:
Fundamental purpose of the present invention addresses the above problem exactly, it provides a kind of user directly to browse the method (need not the download pictures file, also need not to be decrypted into earlier common picture file) that is placed on the local computer and is placed on the encryption picture file on the computing machine on the internet by the input password.The present invention provides a kind of preservation and browsing pictures document method of safe ready to the user.
The present invention seeks to realize like this: by computer interconnected network, utilize the software systems that are arranged on the client and server, and realize the inventive method.Be that the user inputs password,, submit to the picture file encryption system and encrypt that the picture file after encrypting can be placed on local computer, also can be placed on the internet with the picture file that hope is encrypted.The user need browse when encrypting picture file, and the input same password is opened the encryption picture file and browsed, and the encryption picture file that is placed on the internet also needs to provide the network address of depositing picture.It may further comprise the steps:
1) user inputs password in system, and imports one or many addresses that need the common picture file of encryption;
2) system inputs password as key with the user, common picture file is encrypted to generate encrypt picture file;
3) be placed on the local computer or on the internet computer encrypt picture file;
4) user in system, import and 1) same password, and import the address of the encryption picture file that or many needs open;
5) for the encryption picture file that is placed on the local computer, document data flow is read in to the content of encrypting picture file in system, and the password of importing with the user is a key, the contents decryption of the document data flow that reads in the calculator memory data stream, is converted to image to the content of internal storage data stream again and displays in system;
6) for the encryption picture file that is placed on the internet, the network address that system provides by the user, send the Internet request and read in the network file data stream encrypting the picture file content, and the password of importing with the user is a key, the contents decryption of the network file data stream that reads in the calculator memory data stream, is converted to image to the content of internal storage data stream again and displays in system.
Definition and explanation
The character string that described " password " is made up of a character or a plurality of character.
Described " common picture file " is the file that common picture browsing software can be opened present graphical.
Described " encryption picture file " is meant with the picture file after the method encryption of the present invention.
The employed system of the inventive method is composed as follows: the user cipher input system, picture file encryption system, picture file decryption system, picture is deposited and display systems.This four systems is the software systems according to function setting, can be to be erected on same the computing machine, perhaps is deployed in respectively on the different computing machines that link to each other with the internet.Each subsystem concrete function is as follows: (with reference to figure 1)
A) user cipher input system: the password of user's input is submitted to system.
B) picture file encryption system: system inputs password as key with the user, common picture file is encrypted to generate encrypt picture file.
C) picture file deciphering and display systems: for the encryption picture file that is placed on the local computer, document data flow is read in to the content of encrypting picture file in system, and the password of importing with the user is a key, the contents decryption of the document data flow that reads in the calculator memory data stream, is converted to figure to the content of internal storage data stream again and displays in system; For the encryption picture file that is placed on the internet, the network address that system provides by the user, send the Internet request and read in the network file data stream encrypting the picture file content, and the password of importing with the user is a key, the contents decryption of the network file data stream that reads in the calculator memory data stream, is converted to figure to the content of internal storage data stream again and displays in system.
D) picture storage system: deposit the encryption picture file.
Description of drawings:
Fig. 1 is a system for use in carrying process flow diagram of the present invention
Fig. 2 is the operating environment synoptic diagram of one embodiment of the invention
Embodiment:
Below in conjunction with accompanying drawing, embodiments of the present invention are described.
Fig. 1 represents the running environment of encrypting picture file and showing the embodiment of the method for encrypting picture file.As shown in the drawing, operating environment 10 can comprise one or several computing equipment 11, and this can comprise some personal computers.Each computing equipment 11 can be connected on the network 12.Network 12 generally comprises one or several sub-network that links mutually, and these networks 12 can comprise one or several Local Area Network and/or wide area network (WAN).The webserver 13 is connected on the network 12, and this webserver 13 is deposited picture file.Running environment of the present invention can be any network similarly that exists at present or occur in the future.Need to prove that the user imports cryptographic system, the encryption system of picture file, the storage system of picture file, picture deciphering and display systems can be to be erected on same the computing machine, perhaps are deployed in different from the continuous computing machine in internet respectively.
