In some optional embodiments, as shown in fig. 1, a method for encrypting a local file is provided, which specifically includes the following steps:
s101: a start request for a local file is received.
The start request of the local file comprises one or more of voice instructions, action instructions and input instructions of a user. Here, taking the start request of the local file as a voice instruction as an example, the keyword information in the user voice instruction is identified, and when the acquired keyword information matches with the pre-stored keyword information, the start request of the local file is received. For example, the pre-stored keyword information is "open", "video" and "party building major industry", when the user voice instruction is "please open the video party building major industry", the keyword information in the user voice instruction is determined to be "please", "open", "video" and "party building major industry", and is matched with the pre-stored keyword information, and the user thinks that the start request of the local file is received.
S102: user attribute information of the local file is identified.
When downloading the local file, the user acquires the user information of the local file, and associates the user information of the local file with the storage position information of the local file. The user information of the local file may be a user account or a user account address. In this way, the corresponding user information can be acquired by acquiring the storage location information of the local file. Here, the user information of the local file is taken as the user account as an example. After the corresponding user account is obtained through the storage position of the local file, the user account is sent to a download website of the local file or a user attribute information query center of a download system, and the attribute information of the user account is queried to determine the user attribute information of the local file.
S103: when the user attribute information is a member, allowing the local file to be started; and when the user attribute information is non-member, encrypting the local file.
When the user attribute information of the local file is a member, responding to the starting request of the local file, and allowing the local file to be started; and when the user attribute information of the local file is a non-member, not responding to the starting request of the local file, and encrypting the local file.
Thus, in this optional embodiment, for the local file downloaded to the local, after receiving the start request of the local file, the user attribute information of the local file is verified, when the user attribute information of the local file conforms to the corresponding right, the start request of the local file is responded, the start operation of the local file is allowed, when the user attribute information of the local file conforms to the non-corresponding right, the local file is encrypted, the start operation of the local file is rejected, and the copyright of the resource party can be guaranteed.
In some optional embodiments, as shown in fig. 2, a method for encrypting a local file is provided, which specifically includes the following steps:
s201: a start request for a local file is received.
S202: download source attribute information for the local file is identified.
When downloading the local file, the user acquires the downloading source information of the local file and associates the downloading source information of the local file with the storage position information of the local file. In this way, the corresponding download source information can be acquired by acquiring the storage location information of the local file. After the corresponding downloading source information is acquired through the storage position of the local file, the downloading source information is sent to a downloading website of the local file or a downloading source attribute information query center of a downloading system, and the attribute information of the downloading source information is queried to determine the downloading source attribute information of the local file.
S203: when the downloading source attribute information of the local file is a non-member resource, allowing the local file to be started; and when the downloading source attribute information of the local file is the member resource, identifying the user attribute information of the local file.
When the downloading source attribute information of the local file is a non-member resource, responding to the starting request of the local file and allowing the local file to be started; and when the downloading source attribute information of the local file is the member resource, identifying the user attribute information of the local file.
Optionally, when the download source attribute information of the local file is a non-member resource, identifying the download source attribute information of the local file in the playing process of the local file; and when the downloading source attribute information of the local file is the member resource, identifying the user attribute information of the local file. Therefore, in the playing process of the local file, if the downloading source attribute information of the local file is changed from the non-member resource to the member resource, the playing of the local file can be continued according to the verification result of the user attribute information of the local file, and the copyright of the resource side is guaranteed.
S204: when the user attribute information is a member, allowing the local file to be started; and when the user attribute information is non-member, encrypting the local file.
Thus, in this optional embodiment, after receiving the start request of the local file, if the download source attribute information of the local file is a non-member resource, the start operation of the local file is allowed in response to the start request of the local file, and if the download source attribute information of the local file is a member resource, the user attribute information of the local file is verified. On one hand, because the member resources and the non-member resources are updated and changed continuously, for example, the member resources are used when some local files are downloaded, and are changed into the non-member resources when playing for a period of time, while the non-member resources are used when some local files are downloaded, and are changed into the member resources when playing for a period of time, before the user attribute information verification operation of the local files, the verification operation of the downloading sources of the local files is carried out, and the benefits of both the user and the resource party are ensured; on the other hand, when the download source attribute information of the local file is the non-member resource, the starting operation of the local file is directly allowed, the verification operation of the user attribute information of the local file is omitted, and the starting fluency of the local file is improved.
In some optional embodiments, as shown in fig. 3, a method for encrypting a local file is provided, which specifically includes the following steps:
s301: a start request for a local file is received.
S302: user attribute information of the local file is identified.
S303: when the user attribute information is a member, allowing the local file to be started; and when the user attribute information is non-member, encrypting the local file.
S304: and acquiring the operation information of the user.
Here, when the user attribute information is a non-member, the local file is encrypted, the user is prompted to perform a related operation, and the operation information of the user is captured. For example, when the user attribute information is a non-member, a prompt message of "non-member cannot play member resources" is displayed, the user is guided to perform an operation of changing the user attribute information to a member or an operation of purchasing the play right of the local file, and the actual operation information of the user is monitored and captured.
S305: and when the operation information of the user is to change the user attribute information into a member, or when the operation information of the user is to purchase the playing right of the local file, decrypting the local file.
Optionally, changing the user attribute information to be a member specifically includes: the user attribute information is changed to the member by purchasing the member, or the user attribute information is changed to the member by participating in the member presenting activity.
Therefore, after the user obtains the playing authority of the local file, the local file is decrypted, the starting operation of the local file is allowed in response to the starting request of the local file, and the user can browse the local file conveniently.
S306: and when the operation information of the user is not acquired within the set time, acquiring the basic information of the local file.
Here, the basic information of the local file includes a file type and a content profile of the local file. When downloading the local file, the user acquires the basic information of the local file and associates the basic information of the local file with the storage position information of the local file. In this way, the corresponding basic information can be acquired by acquiring the storage location information of the local file.
S307: and acquiring similar files of the local file according to the basic information of the local file.
Here, the basic information of the similar file is similar to that of the local file. Specifically, the file type of the similar file is the same as the file type of the local file, and the keywords in the content profile of the similar file are the same as or partially the same as the keywords in the content profile of the local file. For example, the format of the file type of the local file is "rm" (a video format), the keywords in the content introduction are "china", "reform" and "open", the format of the file type of the similar file is "rm", and the keywords in the content introduction are "china", "reform" and "open", or "china", "reform", or "china".
Optionally, the network file with the highest matching degree between the keywords in the content profiles of the network files and the keywords in the content profiles of the local files is obtained as the similar file of the local files.
S308: and acquiring and displaying basic information of similar files.
Here, after obtaining the similar file of the local file, the file type and the content profile of the similar file are obtained and displayed to the user, so that the user decides whether to browse the similar file based on the basic information such as the file type and the content profile of the similar file.
Thus, in this optional embodiment, when the user attribute information is a non-member, the local file is encrypted, and when the user obtains the play right of the local file, the local file is decrypted, so that the user can conveniently browse the local file, and when the user does not obtain the play right of the local file, the similar file whose download source attribute information is a non-member resource is obtained according to the basic information of the local file, and the user can determine whether to use the similar file as a substitute file of the local file according to the basic information of the similar file, so that the user can still obtain information equivalent to the local file by browsing the similar file without changing the user attribute information as a member or purchasing the play right of the local file, and the user experience is improved without infringing the copyright of the resource party.
In some optional embodiments, encrypting the local file specifically includes: performing primary encryption on the data of the local file; and carrying out secondary encryption on the key for encrypting the data of the local file. Correspondingly, decrypting the local file specifically includes: performing secondary decryption on the key for encrypting the data of the local file; and carrying out primary decryption on the data of the local file.
Therefore, the encryption key is encrypted and packaged, so that the data of the local file can be prevented from being easily cracked due to key leakage, the encryption safety of the local file is improved, and the two-stage encryption operation is respectively positioned at different application levels without influencing functions. In addition, the decryption operation and the encryption operation adopt a symmetrical mode, and the complexity and the workload of the decryption operation are reduced.
