Description

A METHOD AND A DEVICE FOR DATA PROCESSING

CROSS-REFERENCE TO RELATED APPLICATIONS

[001] This application claims priority to Chinese Patent Application No. 201310334412.4, filed on August 2, 2013, which is hereby incorporated by reference in its entirety.

FIELD

[002] The present disclosure relates to the field of the Internet technologies, particularly to a method and a device for data processing.

BACKGROUND

[003] With the existing art, before application can be installed on a terminal running on an Android™ system, the Android application package (APK) needs to be run on the terminal. A user can download APKs by using a large number of APK download links provided on existing websites. However, due to an original data error or network transmission error that may occur during APK download, the downloaded APK may not be the APK requested by the user and consequently fails to be installed locally.

[004] Generally, for the sake of commercial profits, operators add downlinks to APKs, Such a practice is called download hijack. Download hijack often causes errors in downloaded file streams, namely, original data errors. For example, the downloaded APK may be a download software APK, instead of the game APK requested by the user. Currently, the Message Digest Algorithm 5 (MD5) is configured to check whether an APK downloaded by a user is the APK requested by the user. In addition, an APK is partitioned into multiple sub-packages according to the specified data size for convenient transmission on a network. This gives rise to the problem that some of these sub- packages may get lost during the transmission. In such as case, the APK received by the terminal is incomplete. An APK is a compressed file in the *.zip format. Therefore, currently, the Cyclic

Redundancy Check (CRC) is configured to check whether any part of a user-downloaded APK is lost.

[005] Even if the APK downloaded by a user is complete and also the APK requested by the user, parsing of the APK may fail due to a system problem, leading to an APK installation failure. As a result, the success rate of local APK installations is low.

SUMMARY

[006] A method and a device for data processing provided by the present disclosure, capable of solving the problem of low success rates of local APK installations.

[007] In one aspect, the present disclosure provides a method for data processing implemented in a device including a processor. The method includes: verifying a stored target package based on a preset encrypted hash function; if said verification is successful, performing error detection on said target package according to a preset error detection standard; if said error detection is successful, checking the validity of said target package by invoking a verification function, said validity check being configured to check whether said target package can be parsed; if said validity check is successful, installing said target package.

[008] In another aspect, the present disclosure further provides a device for data processing. The device includes a hardware processor and a non-transitory storage medium. The non-transitory storage medium is configured to store units including: a verification unit, an error detection unit, a validity check unit, and an installation unit. The verification unit is configured to verify a target package stored in the storage unit based on a preset encrypted hash function. The error detection unit is configured to, if the verification performed by said verification unit is successful, perform error detection on said target package based on a preset error detection standard. The validity check unit is configured to, if the detection performed by said error detection unit is successful, perform validity check on said target package by invoking a verification function, said validity check being configured to check whether said target package can be parsed. The installation unit is configured to, if the check performed by said validity check unit is successful, install said target package.

[009] The method and device provided by the present disclosure for data processing may be configured to verify a stored target package based on a preset encrypted hash function, said target package being a package sent by a network-side server according to a user request; if said

verification is successful, perform error detection on said target package according to a preset error detection standard; if said error detection is successful, perform validity check on said target package by invoking a verification function, said validity check being configured to check whether said target package can be parsed; if said validity check is successful, install said target package. Verification of a stored target package based on a preset encrypted hash function can ensure that the downloaded target package is the requested package, namely, ensuring that the target package is unique. Error detection on said target package according to a preset error detection standard can ensure that the target package is integral. Validity check on said target package by invoking a verification function can ensure that the target package is valid. The existing art only checks either the integrity or the uniqueness of the target package. By checking the uniqueness, integrity, and validity of target packages, the present disclosure can improve the check efficiency, capable of eliminating, by a larger proportion compared with the existing art, the target packages that cannot be installed. If the target package passes the above-mentioned three checks, said target package is installed. Thus, the installation success rate increases. In addition, unnecessary installation operations are avoided and system resources saved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part, but not all, of the embodiments of the present disclosure. On the basis of the embodiments of the present disclosure, all other embodiments acquired by those of ordinary skill in the art under the precondition that no creative efforts have been made shall be covered by the protective scope of the present disclosure.

[027] In order to make the objectives, technical solutions, and advantages of the present disclosure more comprehensible, the present disclosure is further described in detail below with reference to embodiments and the accompanying drawings.

[028] Obviously, embodiments are only described partly below, rather than all of them. Any other embodiment made by person of skill in the art without creative labor is in protection of the disclosure.

[029] In conjunction with the drawings of the embodiments of the present disclosure, the following clearly and completely describes the technical solutions provided by the embodiments of the present disclosure. Obviously, the described embodiments are only some, but not all, of the embodiments of the present disclosure. All the other embodiments which are obtained by those of ordinary skill in the art on the basis of the embodiments of the present disclosure without creative work shall fall within the protection scope of the present disclosure.

[030] The embodiments of the present disclosure provide a data processing method, and said method is applicable to terminals such as smartphones and tablet PCs. As shown in Figure 1, said method comprises:

[031] Step 101 : Verify a stored target package based on a preset encrypted hash function, the target package being a package sent by a network-side server according to a user request.

[032] Verification of the target package can determine whether the received target package is the package requested by the user. If the target package passes the verification, the verification is successful and the received target package is the package requested by the user. Otherwise, the verification fails and the received target package is not the package requested by the user.

[033] During the verification, the target package is encoded on the basis of the hash function to obtain a string. The network-side server encodes the package requested by the user based on the same hash function to obtain another string. The data encoded using the hash function is unique. Therefore, if the string obtained by means of encoding on the terminal is the same as the string obtained by means of encoding on the network-side server, the target package received by the terminal is the package requested by the user.

[034] The string obtained by means of encoding is a hash, which is a message digest. Generally, a hash has a fixed length, which is much smaller than that of the encoded package. A vigorously- encrypted hash must be irreversible. None of the original information about the encoded package can be deduced by using a hash result. Optionally, one-way hash functions include the MD5 and Secure Hash Algorithm (SHA). [035] Step 102: If the verification is successful, perform error detection on the target package according to a preset error detection standard.

[036] The preset error detection standard is the same as the compression mode adopted to generate the target package. Preferably, error detection is performed on the target package based on the CRC. When error detection is performed on the basis of the CRC, a CRC algorithm is selected according to the number of bits of the system running on the terminal. For example, in the case of a 32-bit system, the CRC32 algorithm is selected, in the case of a 64-bit system, the CRC64 algorithm is selected.

[037] Optionally, error detection is performed on the target package based on parity check.

[038] Step 103 : If the error detection is successful, check the validity of the target package by invoking a verification function, the validity check being configured to check whether the target package can be parsed.

[039] If an Android system runs on the terminal, a preset function in the Package Manager class is invoked. Based on a parameter, the function checks whether the target package can be parsed by the system. The preset function is the information acquisition function getPackagelnfo in the Package Manager class.

[040] Step 104: If the validity check is successful, install the target package.

[041] When the target package is an APK, if the target package passes the checks performed in steps 101 to 103, the target package is installed.

[042] The data processing method provided by the present disclosure can be configured to verify a stored target package based on a preset encrypted hash function, said target package being a package sent by a network-side server according to a user request; if said verification is successful, perform error detection on said target package according to a preset error detection standard; if said error detection is successful, perform validity check on said target package by invoking a verification function, said validity check being configured to check whether said target package can be parsed; if said validity check is successful, install said target package. Verification of a stored target package based on a preset encrypted hash function can ensure that the downloaded target package is the requested package, namely, ensuring that the target package is unique. Error detection on said target package according to a preset error detection standard can ensure that the target package is integral. Validity check on said target package by invoking a verification function can ensure that the target package is valid. The existing art only checks either the integrity or the uniqueness of the target package. By performing uniqueness check, integrity check, and validity check on target packages, the present disclosure can improve the check efficiency, capable of eliminating, by a larger proportion compared with the existing art, the target packages that cannot be installed. If the target package passes the above-mentioned three checks, said target package is installed. Thus, the installation success rate increases. In addition, unnecessary installation operations are avoided and system resources saved.

[043] The embodiments of the present disclosure provide another data processing method to further describe the method as shown in Figure 1. Said method, before step 101 "verifying a stored target package based on a preset encrypted hash function, said target package being a package sent by a network-side server according to a user request", further comprises:

[044] Step 202: Receive a user-trigged selection instruction, which is configured to select the target package to be downloaded.

[045] The user clicks the download link of the target package on the download page displayed on the terminal, triggering a selection instruction.

[046] Step 202: Send to the network-side server an acquisition request corresponding to the selection instruction, the acquisition request being configured to obtain the target package.

[047] When the user-triggered selection instruction is received, an acquisition request is sent to the network-side server to obtain the target data specified by the selection instruction. For example, when a user clicks a software download link, triggering a selection instruction, an acquisition request is sent to the network-side server to request the server for download of the package corresponding to the link.

[048] Step 203 : Receive the target package and verification string sent by the network-side server, the verification string being a string generated by encoding the target package based on the preset encrypted hash function.

[049] Based on the preset encrypted hash function, the network-side server encodes the target package requested by the acquisition request to obtain a verification string, and sends the verification string along with the target package to the terminal.

[050] Step 204: Save the target package and verification string.

[051] On receiving the target package and verification string, the terminal saves the target package and verification string.

[052] The data processing method provided by the embodiments of the present disclosure can be configured to send an acquisition request to the network-side server according to the user request, receive and save the target package and verification string sent by the network-side server, providing an operation object for subsequently checking whether the target package is complete and valid.

[053] The embodiments of the present disclosure provide another data processing method to further describe the method as shown in Figure 1. As shown in Figure 3, step 101 of verifying a stored target package based on a preset encrypted hash function can be implemented as follows:

[054] Step 301 : Encode a stored target package based on a preset encrypted hash function to obtain the target string. [055] The preset encrypted hash functions may include MD5, MD4, MD3, and SHA-1.

[056] For example, a typical application of MD5 is to generate a message digest of a message, thus preventing message falsification. In the embodiments of the present disclosure, the message is the target package and the generated message digest is the target string. Treating the entire target package as a text message, MD5 uses an irreversible string conversion algorithm to generate a unique MD5 message digest, namely, the target string.

[057] Step 302: Check whether the target string matches the verification string.

[058] The network-side server uses the same MD5 algorithm to encode the requested package and obtain the verification string. Therefore, if the target string matches the verification string, the downloaded target package is consistent with the requested package.

[059] The data processing method provided by the embodiments of the present disclosure can be configured to encode the target package and obtain the target string. If the target string matches the verification string, the target package is consistent with the requested package.

[060] The embodiments of the present disclosure provide another data processing method to further describe the method as shown in Figure 1. As shown in Figure 4, step 102 of performing error detection on the target package according to a preset error detection standard can be implemented as follows:

[061] Step 401 : Partition the target package to generate at least two target sub-packages.

[062] The target package is partitioned according to the specified data size. The format of each target sub-package obtained through partitioning is the same as the format of the target package. For example, after the target package, which is an APK, is partitioned, the format of each target sub- package is the same as that of the APK, namely, the *.zip format. The size of a target sub-package is decided by the memory capacity and the running capability of the terminal. For example, a 1 MB APK is partitioned into ten target sub-packages, each of which is 100 KB in size. In this case, the memory performs error detection on these ten target sub-packages respectively, shortening the time required for error detection compared with the error detection directly performed on the APK.

[063] Step 402: Perform error detection on each target sub-package based on a preset error detection standard.

[064] Parallel error detection or serial error detection is performed on each target sub-package based on a preset error detection standard.

[065] The format of each target sub-package is the same as the format of the target package. Therefore, a preset error detection standard is configured to perform error detection on both the target package and target sub-packages.

[066] In this case, step 103, namely, checking the validity of the target package by invoking a verification function if the error detection is successful, can be implemented as follows: [067] Step 403 : If the error detection on each target sub-package is successful, invoke a verification function to perform validity check on the target package.

[068] If the error detection on all the target sub-packages is successful, it is determined that the error detection on the target package is successful. In this case, a verification function is invoked to perform validity check on said target package.

[069] With the data processing method provided by the embodiments of the present disclosure, the target package can be partitioned into multiple target sub-packages so that each target sub- package is much smaller than the target package. Thus, the complexity of and system resource consumption in error detection are reduced to improve the efficiency of error detection.

[070] The embodiments of the present embodiment provide another data processing method to further describe the method as shown in Figure 1. As shown in Figure 5, said method further comprises:

[071 ] Step 151 : Display an error report if the check fails.

[072] If the check is successful, step 102 is performed; if the check fails, step 151 is performed.

[073] Step 152: Display an error report if the error detection fails.

[074] If the error detection is successful, step 103 is performed; if the error detection fails, step

152 is performed.

[075] Step 153 : Display an error report if the validity check fails, the error report being configured to inform the user that the package cannot be run.

[076] If the error detection is successful, step 104 is performed; if the error detection fails, step

153 is performed.

[077] An error report can contain audios, images, or text. For example, an error report is displayed in a pop-up window, showing the text "APK installation failed. Please download again."

[078] With the data processing method provided by the embodiments of the present disclosure, when verification, error detection, or validity check fails, an error report is displayed, informing the user about the installation of the target package; meanwhile, the installation of the original package is canceled to save system resources.

[079] Further, said step of verifying a stored target package based on a preset encrypted hash function comprises verifying the stored target package based on the MD5.

[080] Said step of performing error detection on said target package according to a preset error detection standard comprises performing error detection on said target package according to the CRC.

[081] Said step of invoking a verification function to perform validity check on said target package comprises performing validity check on said target APK by invoking a preset function in the Android Package Manager class.

[082] Said target package is an Android package. [083] In a preferred embodiment of the present disclosure, if the target package is an APK, MD5 is used as the preset encrypted hash function; CRC is used as the preset error detection standard; the invoked verification function is a preset function in the Android Package Manager class.

[084] The embodiments of the present disclosure further provide a data processing device as shown in Figure 6. The device 600 includes a non-transitory storage medium 610 and a hardware processor 620. The non-transitory storage medium 610 is accessible to the hardware processor 620 and is configured to store units including:

Verification of a stored target package based on a preset encrypted hash function can ensure that the downloaded target package is the requested package, namely, ensuring that the target package is unique. Error detection on said target package according to a preset error detection standard can ensure that the target package is integral. Validity check on said target package by invoking a verification function can ensure that the target package is valid. The existing art only checks either the integrity or the uniqueness of the target package. By performing uniqueness check, integrity check, and validity check on target packages, the present disclosure can improve the check efficiency, capable of eliminating, by a larger proportion compared with the existing art, the target packages that cannot be installed. If the target package passes the above-mentioned three checks, said target package is installed. Thus, the installation success rate increases. In addition, unnecessary installation operations are avoided and system resources saved.

[098] a verification sub-unit 6112, configured to check whether said target string obtained by said encoding sub-unit 6111 matches said verification string received by the receiving unit 615.

[099] The data processing device 600 provided by the embodiments of the present disclosure can be configured to encode the target package and obtain the target string. If the target string matches the verification string, the target package is consistent with the requested package.
