Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In the prior art, the storage manner of the picture information corresponding to the POI in the map is as follows: the picture data of the picture is stored in the cloud storage, and the picture associated information (POI type information, POI association relation, POI description information and the like) is stored in the database. It can be seen that the storage mode of the POI picture in the current map is that the POI picture is associated with, and only the related picture tag is added for cloud storage, and then the cloud carries out consistency check with the picture encryption check code.

When a user views the POI pictures, the user can only select all the pictures or view all the pictures according to the labels, and the time of picture formation, the time situation of the picture formation and the change before and after the picture formation can only be guessed according to the picture album.

The above solution can accomplish the storage of POI related pictures, but it has the following disadvantages:

(1) the picture associated information is stored in a database mode, the picture is not added with the related information, and the picture description is inaccurate and the information is inconsistent with the picture when the database information is changed;

(2) the pictures are stored in the cloud storage, and once a person maliciously modifies or deletes data in the cloud storage, the information associated with the database still exists, and the pictures are lost, so that the picture chain is empty;

(3) when information in the database is deleted, related data in the cloud storage needs to be deleted synchronously. However, the situation that the pictures in the cloud storage are not deleted easily occurs in the scheme, so that a large amount of redundant data occurs in the cloud storage.

In view of the above problems, embodiments of the present application provide a method for processing a point of interest map, which may be implemented. The point of interest map processing method is described in detail below in several specific implementations.

Fig. 1 is a schematic view of an application scenario of a point of interest picture processing method according to a first embodiment of the present application. As shown in fig. 1, the method for processing a point of interest picture provided by this embodiment is applied to a distributed storage system, where after a picture file is generated from a point of interest picture and a point of interest picture, the picture file is sliced, and the sliced data is distributed and stored. When different interest pictures are updated in different time periods for the same interest point, the link address of the previous picture can be added into each picture file, so that the safety of picture data is guaranteed, and a time sequence chain of the interest point pictures can be established.

In addition, the distributed database can be accessed through different terminal devices (such as a notebook computer, a personal computer, and a smart phone), for example, a link address of the first slice data stored in the general database in the target picture file can be obtained by inputting identification information of the interest point (such as a name of the interest point, a number of the interest point, and other attribute information of the interest point), the next slice data is sequentially obtained through the chain connection relationship among the slice data until all slice data are obtained, and then a complete interest point picture is displayed, so that the interest point picture can be effectively prevented from being maliciously tampered.

Fig. 2 is a schematic flowchart of a point of interest map processing method according to a second embodiment of the present application. As shown in fig. 2, the method for processing a point of interest map provided by this embodiment includes:

step 101, receiving an acquisition request of the point of interest data.

Specifically, when the point of interest picture needs to be displayed, for example: the method can be implemented by initiating an acquisition request of the point of interest data on the map when a user finds a hotspot location of a mall, a hospital, a parking lot, and the like, wherein identification information of the point of interest (for example, a name of the point of interest, a number of the point of interest, and other attribute information of the point of interest, and the like) may be included in the acquisition request.

In a possible scenario, when the user needs to navigate to the parking lot a, the door map of the parking lot entrance may be displayed immediately before the user arrives at the parking lot entrance, and at this time, the identification information of the point of interest in the acquisition request may be the name of the parking lot a.

In yet another possible scenario, when the user needs to find the B restaurant, the name of the B restaurant may be entered in the map and an acquisition request for the point-of-interest data may be initiated to acquire the door map of the B restaurant.

And 102, acquiring a target picture file according to the acquisition request.

In this step, a target picture file may be obtained according to the obtaining request, where the target picture file includes the point of interest picture and the associated information of the point of interest picture. It is to be understood that the point-of-interest map may be a facial map of the point of interest, and the associated information of the point-of-interest map may be a shooting time of the facial map of the point of interest.

It should be noted that the association information of the point of interest pictures may be stored in the point of interest pictures to form the target picture file, and the association information of the point of interest pictures may also be stored in an additional database. Optionally, the association information of the point of interest picture may be encrypted and then stored in the point of interest picture to form a target picture file.

And step 103, displaying the interest point picture and the associated information.

In this step, after the target picture file is acquired according to the acquisition request, the point of interest picture and the associated information may be displayed. Specifically, the face map corresponding to the interest point and the time taken by the face map may be displayed at a predetermined position on the map, for example, the face map of the parking lot a and the time taken by the face map may be displayed below the map, or the face map of the restaurant B and the time taken by the face map may be displayed below the map.

On the basis of the above embodiments, fig. 3 is a schematic flow chart of a point of interest map processing method according to a third embodiment of the present application. As shown in fig. 3, the method for processing a point of interest map provided in this embodiment may further include:

step 201, receiving an update request of the point of interest data.

Specifically, an update request of the point of interest data is received, where the update request includes an interest point update picture and update association information of the interest point update picture.

For example, for the door face map currently stored in restaurant B and taken in month 6 of 2017, due to the fact that the time is long, restaurant B may be refitted, and therefore, the door face may be changed greatly. At this time, the server may accept reception of an update request for the B restaurant, in which the B restaurant update picture and update-related information of the B restaurant update picture are included, for example, a door map taken in 3 months in 2019.

By receiving the update request of the interest point data and generating the update picture file according to the interest point update picture and the update associated information in the update request, the data of the same interest point can be updated in stages, so that a map user can acquire the latest picture information.

Step 202, generating an updated picture file according to the interest point updated picture and the updated associated information.

Optionally, after the picture is updated according to the interest points and the updated associated information is generated into the updated picture file, a forward link and a backward link may also be generated. Specifically, the backward link is used to connect the current updated picture file to the last updated picture file, and the updated picture file includes the backward link. For example, the B-restaurant picture file corresponding to month 3 in 2019 includes a forward link for linking the B-restaurant picture file corresponding to month 3 in 2019 to the B-restaurant picture file corresponding to month 6 in 2017, and the B-restaurant picture file corresponding to month 6 in 2017 includes a backward link for linking the B-restaurant picture file corresponding to month 6 in 2017 to the B-restaurant picture file corresponding to month 3 in 2019.

Fig. 5 is a schematic diagram of a picture file data link structure provided in a fifth embodiment of the present application, and fig. 7 is a schematic diagram of displaying a point of interest picture and associated information in the embodiment shown in fig. 5. As shown in fig. 5 and 7, the 3 picture files (e.g., the facia map 1, the facia map 2, and the facia map 3) corresponding to one interest point may be arranged in the order of time of generation. The back link SH11 is included in the door facing fig. 1, and the back link SH11 is used to link the door facing fig. 1 to the door facing fig. 2. The front link SH01 and the back link SH21 are included in the door face fig. 2, wherein the front link SH01 is used to link the door face fig. 2 to the door face fig. 1, and the back link SH21 is used to link the door face fig. 2 to the door face fig. 3. In addition, the front link SH11 and the back link SH31 are included in the door face fig. 3, wherein the front link SH11 is used for linking the door face fig. 3 to the door face fig. 2, and the back link SH31 is used for linking the door face fig. 2 to the next door face fig.

The forward link and the backward link are generated, so that a chain structure between the picture files is established according to the time sequence, the picture files have the time sequence relation due to the fact that the picture files record the front picture file and the back picture file, the time information of the POI attached picture can be effectively displayed according to the time sequence relation, and when all the picture files of one POI can be stored according to the set of mode, the historical change of one POI can be effectively and reasonably displayed through the picture.

In addition, after the update picture file is generated, the update picture file may be further sliced to form a data slice set, where the data slice set includes a plurality of data slices arranged in order, and a first link and a second link are generated for a first data slice, where the first link is used to connect the first data slice to a previous data slice, and the second link is used to connect the first data slice to a second data slice, where the second data slice is a next data slice of the first data slice in the data slice set.

With continued reference to fig. 5, for the door face fig. 1, the data slicing operation may be performed on the door face fig. 1, for example, the door face fig. 1 may be divided into 5 data slices (data slice 1, data slice 2, data slice 3, data slice 4, and data slice 5), while a first link SH01 and a second link SH02 are generated for the data slice 1, and SH02 and SH03 are allocated for the data slice 2, where SH02 is used to link the data slice 1 and the data slice 2. Data slice 3 is assigned SH03 and SH04, where SH03 is used to link data slice 2 with data slice 3. Data slice 4 is assigned SH04 and SH05, where SH04 is used to link data slice 3 with data slice 4. If data slice 5 is the last data slice, it is simply allocated SH05 for linking forward to data slice 4.

Furthermore, the backward link in the door face fig. 1 may be set to be SH11 of the first data fragment in the door face fig. 2, so that the door face fig. 2 may be acquired through the door face fig. 1 and SH11, while the forward link set in the door face fig. 2 may be SH01 of the first data fragment in the door face fig. 1, so that the door face fig. 1 may be acquired through the door face fig. 2 and SH01, and the forward link set in the door face fig. 2 may be SH21 of the first data fragment in the door face fig. 3, so that the door face fig. 3 may be acquired through the door face fig. 2 and SH 21.

The image file is sliced to form a data slice set, and the chain connection relation of each data slice is established in a mode of storing the link of the previous data slice and the link of the next data slice in each data slice, so that each data slice can be sequentially acquired to generate and display the image of the interest point.

In addition, after the first link and the second link are generated for the first data segment, a first link hash value may be generated according to the first link and a preset hash algorithm, and a second link hash value may be generated according to the second link and the preset hash algorithm, where the first data segment includes the first link hash value and the second link hash value, and the second data segment includes the second link hash value.

That is, for the door face fig. 1, a first concatenated hash value SH01 and a second concatenated hash value SH02 are generated for the data slice 1, and SH02 and SH03 are allocated for the data slice 2, wherein SH02 is used for linking the data slice 1 and the data slice 2. Data slice 3 is assigned SH03 and SH04, where SH03 is used to link data slice 2 with data slice 3. Data slice 4 is assigned SH04 and SH05, where SH04 is used to link data slice 3 with data slice 4. If data slice 5 is the last data slice, it is simply allocated SH05 for linking forward to data slice 4.

The link hash value is generated by encrypting the link, and the picture can be generated according to all slice data again only after all the slice data hash values of the picture corresponding to the interest point are collected, so that the picture of the interest point is prevented from being maliciously tampered.

In addition, fig. 6 is a schematic diagram of a data storage structure of the encryption database in the embodiment shown in fig. 5. As shown in fig. 5 to fig. 6, each data slice in the data slice set may be further stored into a plurality of different link addresses, a mapping relationship between the link address of each data slice and the corresponding link hash value is stored into the encrypted database, and a first link hash value is stored into the universal database, where the first data slice is a first data slice in the data slice set, and the first link is a backward link.

By storing each data slice in the data slice set into a plurality of different link addresses, distributed multi-storage of all data slices is realized, and the actual link addresses of the data slices corresponding to the link hash values are also recorded into the distributed encryption database. However, since the related information storage only records one mapping relationship, and has no other meaning, if there is no correct decryption method or data slice integration method, the corresponding point of interest picture cannot be restored and processed.

In addition, the picture link address existing in the general database is only the link hash value of the first piece of slice data corresponding to the picture slice data, and the point of interest picture can be generated again according to the full slice data only after all the slice hash values of the corresponding pictures are collected, so that the point of interest picture is prevented from being maliciously tampered.

And the picture files record the front picture file and the rear picture file, so that the picture files have a time sequence relationship, the time information of the POI attached picture can be effectively displayed according to the time sequence relationship, and when all the picture files of one POI can be stored in the set of mode, the picture can effectively and reasonably display the historical change of one POI.

And if the data of the point of interest picture corresponding to the POI is modified, but the hash information corresponding to the picture is not modified, the historical condition of the picture can be restored again according to the time sequence information contained in the picture file, because the picture file stores the relevant associated information, the picture does not depend on other databases strongly.

In other words, the POI picture can encrypt and record partial relevant and important related information of the picture, the picture can be guaranteed not to be damaged to the maximum extent under the condition that the database is abnormal, the POI picture is stored in slices, if a network attack occurs, a user can not restore the picture only by means of partial picture slices, meanwhile, due to the fact that the slices are stored in a distributed mode in multiple places, data fluctuation occurs in only one place, restoration can be performed through storage in other regions, and the POI picture loss condition cannot occur. In addition, because the POI picture has a chain structure, when data is redundant, the whole data can be pulled out for processing through the chain change of the picture, and the redundancy of the picture is effectively reduced.

Fig. 4 is a schematic flowchart of a processing method of a point of interest map according to a fourth embodiment of the present application. As shown in fig. 4, the method for processing a point of interest map provided by this embodiment includes:

step 301, receiving an acquisition request of the point of interest data.

Step 302, obtaining a first link hash value according to the identification information of the interest point.

And 303, acquiring a first link address of the first data slice according to the first link hash value.

Step 304, a first data slice is obtained according to the first link address.

Step 305, obtaining a second link address of the second data slice according to the second link hash value in the first data slice.

And step 306, acquiring a second data slice according to the second link address.

And 307, generating a target picture file according to the acquired data slice set.

And step 308, displaying the point of interest picture and the associated information.

The picture link address existing in the general database is only the link hash value of the first piece of slice data corresponding to the picture slice data, and after the acquisition request of the point of interest data is acquired, the first link hash value can be acquired according to the identification information of the point of interest, that is, the link hash value of the first piece of slice data of the slice data is acquired first. Then, since the slice data between the POI pictures and in the same POI picture have a chain structure, subsequent data slices can be obtained at one time according to the link hash value of the first slice data, and the point of interest picture is generated according to the full slice data after all the slice hash values of the corresponding pictures are collected.
