Based on the mobile terminal hardware structure and the communication device structure, the invention provides each embodiment of the cleaning method for the application browsing record.

Referring to fig. 3, the present invention provides a method for cleaning application browsing records, in a first embodiment of the method for cleaning application browsing records, the method for cleaning application browsing records includes:

step S10, when a selection cleaning instruction for browsing records in each application is received, a cleaning database is formed according to the selection cleaning instruction;

the method for cleaning the application browsing records is applied to a control center of the terminal, and is suitable for cleaning browsing records cached by application software in the terminal, wherein the application software is an application installed in the terminal by a terminal user, such as WeChat, microblog, QQ and the like; the cached browsing records are records in which the terminal user browses and views each application installed in the type and the network is relied on to cache each checked image, document, video and other files. The buffer memory does not distinguish the types of the files, so long as the files which are checked by the terminal user are buffered, when the subsequent terminal user checks the checked files again, the buffered files in the terminal are directly called for display, and the requirement of checking the files again by the terminal user can be met. Also for personnel associated with the end user, such as the end user's girlfriend, men's friends, wife, husband, mother or father, etc.; and when the terminal of the terminal user is taken, opening the application in the terminal, clicking the files such as pictures, documents, videos and the like in the application, if the files are directly opened without downloading, characterizing that the terminal user has checked the files before, and if the files are required to be downloaded without buffering, characterizing that the terminal user has not checked the files before.

Therefore, a person related to the terminal user can judge whether the terminal user looks over the files such as pictures, documents, videos and the like through whether the files are cached in the application; for some files, the end user does not want others to know that they have viewed the file. If the friends are both parties of men and women, the men like to watch the girl pictures and pay attention to investment financing, and the women do not like to watch the girl pictures and pay attention to investment financing; women like to buy clothes and cosmetics, while men do not like the shopping behavior; thus, for a friend of a man, it is not desirable for the friend of a woman to know his or her behavior of watching a picture of girl and paying attention to investment financing, and for the friend of a woman, it is not desirable for the friend of a man to know his or her behavior of browsing shopping videos or shopping popularization pictures. Therefore, in order to meet the demands of different terminal users on terminal use, a mechanism is provided for cleaning the content which the terminal user does not want other personnel to know to view, namely, the terminal user sets the content which needs to be cleaned, and when browsing records related to the content are generated and cached in the application which is subsequently viewed, the cleaning operation is performed on the content in the cache.

Specifically, a selection page for selecting the required cleaning content is arranged in the terminal, and when the terminal user has the requirement of selecting the required cleaning content, the selection page is started by long-pressing or double-clicking an icon corresponding to the selection page. Referring to fig. 4, the selection page includes various application icons, such as a WeChat icon, a QQ icon, etc., capable of supporting cache cleaning, corresponding to the content types, such as pictures or videos, under WeChat, capable of supporting cleaning in various applications included under the various application icons; after selecting an application icon which needs to be cleaned by buffering, the terminal user jumps to a content type page which corresponds to the application icon and can support cleaning, and the content type which needs to be cleaned can be selected in the content type page. Triggering a virtual key for confirming selection after the selection of the application and the content type is completed, and sending a triggering instruction of the virtual key to a control center as a selection cleaning instruction for browsing records in each application; after receiving the instruction for selecting and cleaning, the control center can determine the application and the content type of the buffer cleaning required by the terminal user according to the carried application identifier and the content type identifier. In order to meet the cleaning requirement of the terminal user, the application and the content type for selecting the representation required to be cleaned by the cleaning instruction are formed into a cleaning database, and the cleaning database is used as a cleaning rule to clean the browsing records generated by the subsequent terminal user browsing application.

It should be noted that, the end user can update the cleaning database according to the own requirement; when an application is added to the cleaning database as a new application needing cleaning, a cleaning instruction is triggered to be selected, and the new application can be added to the cleaning database. Correspondingly, when some application is deleted from the cleaning database, the same triggering and selecting cleaning instruction is used for jumping to the selected page through triggering and selecting the cleaning instruction; referring to fig. 5, an application to be deleted among the selected applications displayed on the selected page is dragged to a deletion box to be deleted. According to the autonomous setting of the cleaning database according to the self requirements of the terminal users, the different cleaning requirements of different terminal users can be conveniently realized, and the flexibility of terminal use is improved.

Step S20, when the exit operation of the current browsing application is detected, judging whether a record to be deleted exists in the current browsing record generated based on the current browsing application according to the cleaning database;

further, the application started and viewed by the terminal user at the current moment is used as the current browsing application, and when the exiting operation of the current browsing application sent by the terminal user is detected, the terminal user is stated to finish the browsing operation of the current browsing application, and the generated browsing record for viewing the current browsing application is cached in the terminal. The exit operation may be an operation of directly returning to the main page, or selecting an exit option to exit, or closing a process to exit, which is not limited. A buffer unit is preset in the terminal, and a buffer path for buffering the browsing record to the buffer unit is formed; cache units and cache paths corresponding to different applications are different; in the using process of the current browsing application, a caching unit and a caching path corresponding to the current browsing application are determined, and then the caching path is started to cache the browsing record generated by the current browsing application into the caching unit, so that the browsing record is cached into the terminal.

Furthermore, the browsing record generated by the current browsing application is used as the current browsing record, the content which needs to be cleaned may or may not exist in the current browsing record, the content which needs to be cleaned is used as the record to be deleted, and whether the record to be deleted exists in the current browsing record is determined by the cleaning database. Specifically, the cleaning database is called, and the current browsing record is compared with each item of content set in the cleaning database to generate a comparison result; and judging whether a record to be deleted which needs to be cleaned exists in the current browsing record generated based on the current browsing application according to the comparison result. If the comparison result shows that a certain record exists in the current browsing record and corresponds to a certain content in the cleaning database, the certain record is indicated to exist in the cleaning database and is a record to be deleted; otherwise, if the comparison result shows that any record does not exist in the current browsing record and each content in the cleaning database corresponds, the current browsing record is indicated to be not exist in the cleaning database, and the record to be deleted does not exist in the current browsing record.

And step S30, if the record to be deleted exists in the current browsing record, cleaning the record to be deleted.

Further, if it is determined that the record to be deleted exists in the current browsing record, the record to be deleted is that the terminal user does not want other related personnel to know the content which the terminal user has viewed, so that the record to be deleted is deleted. And generating a cleaning thread according to the cache unit and the cache path of the current browsed record during deletion, and cleaning the record to be deleted by the cleaning thread according to the cache path into the cache unit. After the record to be deleted is cleaned, when the record to be deleted is checked later, the record to be deleted needs to be downloaded again through a network; other personnel related to the terminal user do not know that the terminal user checks the record to be deleted, and unnecessary trouble caused by the fact that the operation behavior of the terminal user on the terminal is known by other related personnel is avoided.

Further, in another embodiment of the method for cleaning a browsing record of the present invention, the step of determining, according to the cleaning database, whether a record to be deleted exists in the current browsing record generated based on the current browsing application includes:

step S21, calling the cleaning database, reading the browsing application identifier of the current browsing application, and judging whether a target application identifier corresponding to the browsing application identifier exists in each application identifier of the cleaning database;

step S22, if a target application identifier corresponding to the browsing application identifier exists, judging whether a record to be deleted exists in the current browsing record according to the browsing content identifier of the current browsing record generated based on the current browsing application;

furthermore, applications requiring cache cleaning and content types requiring cleaning in each application are set in the cleaning database, wherein each application exists in the form of application identification, and the content types in each application exist in the form of cleaning content identification. Meanwhile, each application installed in the terminal carries an identifier representing the uniqueness of each application so as to distinguish among the applications, and the identifier carried in the current browsing application is used as a browsing application identifier. In the process of judging whether a record to be deleted which needs to be cleaned exists in a current browsing record generated by a current browsing application, firstly, calling a cleaning database, and reading all application identifiers in the cleaning database to determine all applications which currently support cache cleaning through all application identifiers; and then reading the browsing application identifier of the current browsing application, comparing the browsing application identifier with each application identifier in the cleaning database, and judging whether a target application identifier corresponding to the browsing application identifier exists in each application identifier, namely judging whether the browsing application identifier exists in the application identifier.

Further, if it is determined that the browsing application identifier exists in the application identifiers, that is, when the target application identifier consistent with the browsing application identifier exists in the application identifiers in the database, the current browsing application viewed by the terminal user is the application needing to be subjected to browsing record cleaning. Considering that the cleaned content is different between different applications supporting cleaning, one part of the browsing records generated based on the applications supporting cleaning is the record needing cleaning, namely the content type added to the cleaning database is selected, and the other part of the browsing records is the record not needing cleaning, namely the content type added to the database is not selected. After determining that the current browsing application is an application requiring cleaning of browsing records, it is also required to determine whether there is a record requiring cleaning in the browsing records generated by the current browsing application, that is, whether there is a record corresponding to the content type added to the cleaning database. Specifically, in order to distinguish between different types of browsing records, each browsing record is allocated with a content identifier for representing the type of each browsing record while each browsing record is generated; and reading the content identifier carried by the current browsing record as a browsing content identifier, and judging whether a record to be deleted which needs to be cleaned exists in the current browsing record according to the browsing content identifier. The step of judging whether the record to be deleted exists in the current browsing record according to the browsing content identifier of the current browsing record generated based on the current browsing application comprises the following steps:

Step S221, reading a browsing content identifier of a current browsing record generated based on the current browsing application, comparing the browsing content identifier with a cleaning content identifier corresponding to the target application identifier, and judging whether a target content identifier corresponding to the browsing content identifier exists in each cleaning content identifier;

step S222, if the target content identifier corresponding to the browse content identifier exists, judging that a record to be deleted exists in the current browse record, and determining the current browse record carrying the target content identifier as the record to be deleted;

step S223, if the target content identifier corresponding to the browse content identifier does not exist, judging that the record to be deleted does not exist in the current browse record.

Furthermore, because the content types required to be cleaned by each application in the cleaning database exist in the form of cleaning content identifiers, after the content identifiers carried by the current browsing record are read as browsing content identifiers, the cleaning content identifiers corresponding to the target application identifiers in the cleaning database are read. And comparing the browse content identifier with each clear content identifier, and judging whether the browse content identifier exists in the clear content identifier, namely judging whether the target content identifier corresponding to the browse content identifier exists in each clear content identifier. If the browse content identifier is determined to exist in the clear content identifier by comparison, the presence of the target content identifier in the clear content identifier indicates that a record to be deleted which needs to be cleared exists in the current browse record, and the record carrying the target content identifier in the current browse record is the record to be deleted. If the fact that the target content identifier does not exist in the clearing content identifier is judged, the fact that the current browsing application is an application needing to clear browsing records is indicated, but the generated browsing records are not the content types needing to be cleared, and therefore the fact that the record to be deleted does not exist in the current browsing records is judged.

And S23, if the target application identifier corresponding to the browsing application identifier does not exist, reading a current browsing record generated based on the current browsing application, and judging whether a record to be deleted exists in the current browsing record according to the matching relation between the current browsing record and the cleaning feature in the cleaning database.

Further, if the browse application identifier is compared with each application identifier in the cleaning database, and it is determined that the target application identifier corresponding to the browse application identifier does not exist in the cleaning database, it is indicated that the current browse application is not an application requiring browse record cleaning. It is considered that although the current browsing application is not set as an application requiring the browsing record cleaning, there may be content in the generated browsing record which is not desired to be known to the relevant person to be viewed by the end user, so that the content in the browsing record needs to be identified and the end user is reminded to clean so as to avoid causing unnecessary trouble. Specifically, in the past, the cleaning database extracts the characteristics of each record to be deleted and generates cleaning characteristics in the process of cleaning each record to be deleted; after determining that the target application identifier does not exist in the cleaning database, further reading the current browsing record generated by the current browsing application, matching the current browsing record with the cleaning characteristics, and judging whether the record to be deleted exists in the current browsing record according to the matching relation between the current browsing record and the cleaning characteristics. The step of judging whether the record to be deleted exists in the current browsing record or not according to the matching relation between the current browsing record and the cleaning feature in the cleaning database comprises the following steps:

Step S231, reading the cleaning features in the cleaning database, comparing the current browsing record with the cleaning features, and generating the similarity between the current browsing record and the cleaning features;

step S232, comparing the similarity with a preset threshold value, and judging whether the matching relationship is successful;

step S233, if the matching relationship is successful, determining that the record to be deleted exists in the current browsing record.

Furthermore, each cleaning characteristic in the cleaning database is read, and the current browsing record and the cleaning characteristic are compared to generate the similarity between the current browsing record and the cleaning characteristic. The similarity characterizes the similarity degree between the current browsing record and the cleaning feature, and the number of similar features and the number of dissimilar features between the current browsing record and the cleaning feature can be determined by extracting the feature of the content corresponding to the current browsing record and comparing the feature with the cleaning feature; and determining a similarity value between the number of similar features and the number of dissimilar features, and taking the similarity value as the similarity. In addition, a preset threshold value representing the similarity is preset, the comparison between the preset threshold value and the similarity is called, and whether the preset threshold value is smaller than or equal to the similarity is judged; if the similarity is smaller than or equal to the similarity, the similarity between the current browsing record and the cleaning feature is higher, and the matching relationship between the current browsing record and the cleaning feature is judged to be successful; if the similarity is not smaller than or equal to the similarity, the similarity degree between the current browsing record and the cleaning feature is lower, and the matching relationship between the current browsing record and the cleaning feature is judged to be matching failure. If the matching relation is successful, the record with higher similarity with the record to be deleted which is cleaned before exists in the current browsing record is indicated; and the record with higher similarity is used as the record to be cleaned in the current browsing record, and the record to be deleted is judged to exist in the current browsing record. And when the matching relation is failed in matching, the fact that no record with higher similarity with the record to be deleted cleaned before exists in the current browsing record is indicated, and the fact that no record to be deleted exists in the current browsing record is judged.

Further, in another embodiment of the present invention, the step of reading the cleaning feature in the cleaning database includes:

step S234, reading a history deletion record of cleaning operation based on the cleaning database, and dividing the history deletion record into a picture attribute record and a video attribute record;

step S235, reading a plurality of picture features in each picture attribute record according to a preset picture rule, and screening common picture features in the plurality of picture features;

step S236, dividing each video attribute record into a plurality of picture frames, reading a plurality of frame features in each picture frame according to the preset picture rule, and screening out common frame features in a plurality of frame features;

step S237, determining the common picture feature and the common frame feature as the cleaning feature.

In this embodiment, each record to be deleted for cleaning the database in the past is read as a history deletion record, and the history deletion record is divided into a picture attribute record and a video attribute record according to different attributes of each record to be deleted; and when the record to be deleted forming the history deletion record is a picture file, dividing the record to be deleted into the type of the picture attribute record, and when the record to be deleted forming the history record is a video file, dividing the record to be deleted into the type of the video attribute record.

In addition, preset picture rules for extracting picture features are preset, for example, the characters of 'beauty', 'investment', 'buying and buying', and the like in the picture are taken as one of the preset picture rules, and the exposed waist, legs, and the like in the picture are taken as one of the preset picture rules. Calling the comparison of each picture in the preset picture rule and the picture attribute record, and reading the characteristic as the picture characteristic in the picture attribute record when the characteristic which is the same as any one rule in the preset picture rule exists in the picture; after the comparison of each picture in each picture attribute record is completed, a plurality of picture features corresponding to each picture in the picture attribute record are formed. Considering that the picture features corresponding to the pictures are different, namely the features related to the picture features are various; and in order to form a unified judging rule, screening the common characteristics in the plurality of picture characteristics to obtain the common picture characteristics for representing the commonality in the picture attribute records. If the investment word is related to a plurality of pictures in the picture attribute record, the investment can be used as a common picture characteristic; when the common picture features are formed, the preset picture number is set, and when at least the pictures with the preset picture number in the picture attribute record contain the same picture features, the picture features are used as the common picture features.

It will be appreciated that a video attribute record consists essentially of pictures from frame to frame, so that the video attribute record may be divided into a plurality of picture frames by the number of frames, i.e., one video attribute record is divided into a plurality of pictures. And then, extracting the characteristics of each picture frame as frame characteristics according to a preset picture rule, and screening the characteristics of each frame to form common frame characteristics corresponding to the video attribute records. The common frame feature is formed in the same manner as the common picture feature, and will not be described in detail herein.

Further, the common picture feature and the common frame feature are formed into the cleaning feature together, and different feature identifiers are used for distinguishing, so that whether the record to be deleted exists in the current browsing record or not can be judged according to the similarity between the cleaning feature and the current browsing record. Specifically, the step of comparing the current browsing record with the cleaning feature, and generating the similarity between the current browsing record and the cleaning feature includes:

step a1, reading an attribute identifier of the current browsing record, and determining a record attribute of the current browsing record according to the attribute identifier;

step a2, when the record attribute is a picture attribute, extracting a current picture feature in the current browsing record, and comparing the current picture feature with the common picture feature to generate a similarity between the current browsing record and the cleaning feature;

Step a3, when the recording attribute is a video attribute, dividing the current browsing record into a plurality of current picture frames, and extracting current frame characteristics in each current picture frame;

and a step a4 of comparing the current frame characteristics with the common frame characteristics to generate the similarity between the current browsing record and the cleaning characteristics.

Still further, the content characterized by the end user browsing in the current browsing record may be a picture, or may be video, or even both; the different content corresponds to different attribute identifications. Reading the attribute identification of the current browsing record to determine the record attribute of the current browsing record according to the attribute identification; when the attribute identifier characterizes the picture content, the recording attribute is a picture attribute, and when the attribute identifier characterizes the video content, the recording attribute is a video attribute. For the picture attribute, extracting current picture features in the current browsing record according to a preset picture rule, comparing the current picture features with common picture features, and determining the number of similar features and the number of dissimilar features between the current picture features and the common picture features; further, adding the number of similar features and the number of dissimilar features to generate an adding result; and then the quantity of the similar features and the addition result are used for carrying out ratio to generate the similarity between the current browsing record and the cleaning feature. For the video attribute, dividing the current browsing record into a plurality of current picture frames; and extracting the current frame characteristics in the current picture frame according to a preset picture rule, comparing the current frame characteristics with common frame characteristics, determining the quantity of similar characteristics and the quantity of dissimilar characteristics between the current frame characteristics and the common frame characteristics, and generating the similarity between the current browsing record and the cleaning characteristics according to the quantity of similar characteristics and the quantity of dissimilar characteristics. The current browsing record is divided into a video file and a picture file to be respectively processed, and the characteristic difference caused by the file difference is fully considered, so that the judgment of whether the record to be deleted exists in the current browsing record can be more accurate.

Further, in another embodiment of the method for cleaning a browsing record of the present invention, if the record to be deleted exists in the current browsing record, the step of cleaning the record to be deleted includes:

step S31, when the record to be deleted exists in the current browsing record, determining a record type corresponding to the record to be deleted;

step S32, reading the record times corresponding to the record types in the cleaning database, and judging whether the record times are larger than a preset time threshold;

step S33, if the number of times of record deletion is larger than a preset number of times threshold, cleaning the record to be deleted;

and step S34, if the number of times of cleaning is not greater than a preset number of times threshold, outputting prompt information for cleaning the record to be deleted, and cleaning the record to be deleted when a cleaning instruction sent based on the prompt information is received.

Understandably, the content viewed by the end user using the application at different times has a difference, so that the generated browsing records have a difference, and the records to be deleted in the current browsing record generated at different times are not identical. In the process of cleaning the record to be deleted, a cleaning reminding mechanism is arranged for improving the cleaning accuracy and the automation degree. Specifically, when it is determined that the record to be deleted exists in the current browsing record, a record type corresponding to the record to be deleted is further determined, wherein the record type represents the type of the record content in the record to be deleted. Meanwhile, the cleaning database counts the record types of the record to be deleted, which are cleaned each time, after determining the record type of the record to be deleted currently, the target type corresponding to the record type in the database to be cleaned is determined, and the record times corresponding to the target type, namely the record times corresponding to the record type in the cleaning database, are read.

In addition, a preset frequency threshold is preset, the recording frequency is compared with the preset frequency threshold, and whether the recording frequency is larger than the preset frequency threshold or not is judged; if the content of the record to be deleted is larger than the content of the record to be deleted, the record to be deleted is cleaned for a plurality of times, and the content of the record to be deleted is determined for the terminal user, so that the record to be deleted is cleaned automatically. When the number of times of recording is not greater than a preset number of times threshold, the fact that the record to be deleted currently cleaned does not have excessive cleaning operation in the past is a content which cannot be determined whether the terminal user needs to clean; and outputting prompt information for cleaning the record to be deleted so as to prompt a terminal user whether to determine that the record to be deleted needs to be cleaned. If the terminal user sends a cleaning instruction according to the prompt information, cleaning the record to be deleted, and simultaneously accumulating and updating the record times of the record type in the cleaning database. If the terminal user sends an instruction of not cleaning according to the prompt information, the record to be deleted is not cleaned, so that error cleaning is avoided.

Further, because the records to be cleaned generated at different moments are not identical, certain newly-appearing cleaning characteristics exist; the current cleaning characteristics in the record to be cleaned are extracted according to a preset image extraction technology, and the current cleaning characteristics are added into the cleaning database to update the cleaning database. When updating, judging whether all the characteristics in the current cleaning characteristics exist in the cleaning database, and if all the characteristics exist in the cleaning database, stopping updating; if a feature in the features does not exist in the cleaning database, the feature is added to the cleaning database to update the cleaning database. The accuracy of the judgment of the subsequent newly-appearing features can be ensured by updating the cleaning database, and the judgment of the subsequent record to be deleted is facilitated.
