Detailed Description
The following describes in detail a specific implementation of an image processing method and an intelligent device according to an embodiment of the present invention with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an intelligent device, as shown in fig. 1, which may include:
a memory 10 configured to store data;
a processor 20 configured to perform the following process:
identifying the acquired image to be processed;
when the image to be processed is judged to comprise a first area and a second area according to the identification result, and the first area comprises privacy information, respectively encrypting the first area and the second area to obtain first sub-encrypted data corresponding to the first area and second sub-encrypted data corresponding to the second area; the privacy information comprises human body information and/or character information, and the encryption degree of the first sub-encryption data is higher than that of the second sub-encryption data;
and coding the first sub-encrypted data and the second sub-encrypted data, determining the encrypted data corresponding to the image to be processed, and transmitting the encrypted data to the memory 10 for storage.
In practical situations, the face information and/or the body information in the image include a biometric feature specific to a person, and the biometric feature has a leakage risk, so that there may be invasion, misuse, and a potential safety hazard of the biometric authentication system itself to the privacy of the user. Moreover, the biometric features are stable and invariant, and once leaked, the biometric features cannot be revoked or updated in the database, which means that there is a high risk of using the biometric features in other systems. Moreover, the uniqueness of the biometric enables organizations with large biometric databases to easily track individual whereabouts. Therefore, due to the high sensitivity of biological features and security considerations, strict security encryption protection of information such as human faces, human bodies and characters in images is necessary.
Therefore, in the embodiment of the present invention, when it is recognized that the image to be processed includes the first area, the first area includes the private information, and the private information includes the human body information and/or the text information, the first area and the second area may be respectively encrypted, so that the encryption degree of the first sub-encrypted data is higher than that of the second sub-encrypted data, that is, the security of the first area is higher than that of the second area, thereby improving the security coefficient of the first area, and reducing the risk of the private information being leaked.
Moreover, because the encryption degree of the first sub-encrypted data is higher than that of the second sub-encrypted data, when the first area and the second area are respectively encrypted, the reduction of the operation speed and the data processing speed can be favorably avoided, and therefore the purposes of high safety and high processing speed can be simultaneously achieved.
In some embodiments, a processor configured to:
encrypting the first area according to an encryption algorithm in a preset first algorithm;
encrypting the second area according to an encryption algorithm in a preset second algorithm;
wherein the encryption degree of the first algorithm is higher than that of the second algorithm.
That is to say, adopt first algorithm when carrying out encryption processing to first region, adopt the second algorithm when carrying out encryption processing to the second region for adopt different algorithms to encrypt respectively different regions, because the encryption degree of first algorithm is higher than the encryption degree of second algorithm, make the encryption degree of the first sub-encrypted data that first region corresponds, can be higher than the second sub-encrypted data that the second region corresponds, thereby make the first region including privacy information have higher factor of safety, thereby reduce the risk that privacy information is revealed.
To illustrate, in some embodiments, the human body information included in the privacy information may be understood as:
any information in the image that is relevant to the human body;
such as but not limited to: the information such as face information, height information, body shape information, worn clothes or dressing style can belong to the protection range of human body information as long as the information can reflect the characteristics of the user and help the identification of the identity of the user.
Specifically, as shown in fig. 2, the image shown in the figure includes two pieces of human body information, so that the region indicated by the solid line box is the first region.
The text information included in the private information may be understood as:
any textual information involved in the image;
such as but not limited to: non-numeric information such as a place name, an address and positioning information, and numeric information such as a telephone, and these literal information may expose the location of the user or the contact information of the user, so that any content related to the literal belongs to the protection range of the literal information.
Specifically, as shown in fig. 3, a landmark for indicating a geographical position is included in the image shown in the figure, which belongs to the text information in the private information, so that the area indicated by the solid frame is the first area.
That is, after the image is identified, the first area and the second area may be identified according to the degree of influence on the privacy of the user, which is specifically shown in table 1.
TABLE 1
Referring to table 1, it can be seen that:
the second area can be understood as an area not including privacy information, and these areas do not include information indicating the identity of the user, so that the second area does not pose a risk to the privacy of the user, and when the second area is subjected to encryption processing, the encryption algorithm in the second algorithm with a lower encryption degree can be used for encryption processing, so as to reduce the complexity of the encryption processing and improve the operation speed and the processing speed.
For the first area, the area including the privacy information may pose a risk to the privacy of the user because the area includes the information for representing the identity of the user; when the first area is processed, the first algorithm with a higher encryption degree can be adopted for encryption processing, so that the security of the first area is improved.
In some embodiments, a processor configured to:
determining the number of the first areas and the position information of the first areas in the image to be processed;
encrypting the position information according to an encryption algorithm in the first algorithm to obtain third sub-encrypted data;
and coding the number of the first areas, the first sub-encrypted data, the second sub-encrypted data and the third sub-encrypted data, determining encrypted data corresponding to the image to be processed, and transmitting the encrypted data to a memory for storage.
Therefore, after the position information of the first area in the image to be processed and the number of the first area are determined, the position information can be encrypted, and then the number of the first area, the first sub-encrypted data, the second sub-encrypted data and the third sub-encrypted data are encoded, so that the information included in the encrypted data is more comprehensive, the encrypted data can be restored into the corresponding image accurately and effectively, and errors in image restoration are reduced.
In some embodiments, a processor configured to:
when the image to be processed does not comprise the first area according to the identification result, encrypting the image to be processed according to an encryption algorithm in the second algorithm to obtain corresponding fourth sub-encrypted data;
and coding the fourth sub-encrypted data, determining the encrypted data corresponding to the image to be processed, and transmitting the encrypted data to a memory for storage.
Since it is recognized that the image to be processed does not include the privacy information, it can be understood that the image to be processed does not include the information representing the user identity, that is, the image to be processed does not include the first area, at this time, the encryption algorithm in the second algorithm with a lower encryption degree may be used for the encryption processing, so as to reduce the complexity of the encryption processing, and improve the operation speed and the processing speed.
In some embodiments, when the number of the first areas, the first sub encrypted data, the second sub encrypted data, and the third sub encrypted data are subjected to the encoding process, the process may be performed according to the following encoding rule:
when the number of the first regions is N, and N is an integer greater than 1:
performing data combination on the N first sub-encrypted data to form first combined data; performing data combination on the second sub-encrypted data, the first combined data and the third sub-encrypted data to form second combined data; when a first preset mark for representing the number of the first areas is determined, performing data combination on the first preset mark and the second combined data;
or, when N is 0:
and when the second preset mark used for indicating that the number of the first areas is zero is determined, performing data combination on the second preset mark and the fourth sub-encrypted data.
The first preset mark represents the number of the first areas, and simultaneously can represent that the number of the first areas needs to be larger than zero; the setting for the first preset flag may be, but is not limited to, setting as: at least one of a number, a letter and a special symbol is sufficient as long as the number of the first regions can be indicated, for example, when the number of the first regions is 1, the corresponding first preset mark may be a mark such as 1, P or #; when the number of the first areas is 3, the corresponding first preset marks may be 3, R or equivalent marks; therefore, the specific arrangement of the first preset mark is not limited herein.
Likewise, for the setting of the second preset flag, the setting may also be, but is not limited to: at least one of a number, a letter, and a special symbol is not limited herein as long as the number of the first regions can be represented as zero.
The encoding rules are exemplified below.
For example, taking the example shown in fig. 2, the number N of the first regions is 2 (i.e. there are two solid boxes, each solid box represents a first region), and it is assumed that the corresponding first preset label for representing that the number of the first regions is 2 is number 2;
to illustrate, if two first areas have a boundary or a partial overlap, the two first areas can be merged and regarded as one first area.
And, the first sub-encrypted data, the second sub-encrypted data, and the third sub-encrypted data may all be: codes comprising numbers, letters and/or special symbols and having a fixed length, such as: the second sub-encrypted data is denoted by a1, and the third sub-encrypted data is denoted by c 1; wherein, since the first area has two, the first sub-encrypted data also has two, which can be respectively denoted by b1 and b 2; at this time:
firstly, performing data combination on the two first sub-encrypted data to obtain first combined data: b1 b 2;
and performing data combination on the second sub-encrypted data, the first combined data and the third sub-encrypted data to obtain second combined data: a1 × b1 × b2 × c 1;
and performing data combination on the first preset mark and the second combined data to obtain data: 2a1 × b1 × b2 × c 1;
therefore, 2a1 × b1 × b2 × c1 may be determined as the encrypted data corresponding to the image to be processed shown in fig. 2.
For another example, assuming that the set number N of the first areas is 0, it is assumed that the second preset flag indicating that the number of the first areas is 0 corresponds to a number 0, and the fourth sub-encrypted data may also be set to, but is not limited to: 3-bit data composed of at least one of numbers, letters, and special symbols, for example, d 1; at this time:
and performing data combination on the second preset mark and the fourth sub-encrypted data to obtain data: 0d 1;
therefore, 0d1 may be taken as the encrypted data corresponding to the image to be processed that does not include the private information.
Of course, the first predetermined flag, the second predetermined flag, and the representation of each sub-encrypted data are not limited to the two examples, and are only illustrated here for ease of understanding.
In addition, when data combination is performed, the arrangement order of each data in the data combination is not limited to the above two examples, and this is only an example, and in an actual situation, the arrangement order of each data may be set according to actual needs as long as the encrypted data corresponding to the image to be processed can be determined according to the encoding rule.
In addition, when setting the encoding rule, the encoding rule is not limited to the encoding rule mentioned in the above, and other encoding rules known to those skilled in the art may be used, such as but not limited to: according to a certain sorting rule, sorting the first preset mark (or the second preset mark), the N first sub-encrypted data, the second sub-encrypted data and the third sub-encrypted data, and then carrying out hash processing on the sorted data by adopting a hash algorithm to obtain a group of codes, namely the encrypted data.
Therefore, the encrypted data corresponding to the image to be processed can be obtained through the encoding rule, the image to be processed can be represented through the encrypted data, uniqueness between the image to be processed and the corresponding encrypted data is realized, and the subsequent obtaining of the corresponding image according to the encrypted data is facilitated.
In practical situations, after the encrypted data corresponding to the image to be processed is obtained, the encrypted data can be stored in the memory, so that the image has higher security during storage, and the risk of leakage is reduced.
If at a certain moment, when a user needs to view an image corresponding to encrypted data stored in a memory, in order to display the image for the user to view, the encrypted data in the memory needs to be read first, decrypted to obtain the image, and then displayed, so that:
in some embodiments, a processor configured to:
reading the encrypted data stored in the memory when the encrypted data needs to be read;
after the encrypted data is decoded, when the image corresponding to the encrypted data is judged to comprise a first area and a second area, respectively determining first sub-encrypted data corresponding to the first area and second sub-encrypted data corresponding to the second area;
respectively carrying out decryption processing on the first sub-encrypted data and the second sub-encrypted data to obtain a first area and a second area;
and processing the first area and the second area to obtain an image corresponding to the encrypted data.
Therefore, through the mode, the image corresponding to the encrypted data can be obtained, so that the user can conveniently process the decrypted image correspondingly.
It should be noted that, when an operation needs to be performed on the images stored in the database, for example, deleting a certain image, all the encrypted data stored in the memory may be decrypted to obtain and display each corresponding image, so that the user can select the image to be deleted.
Therefore, when reading the encrypted data stored in the memory, it is possible to read all the encrypted data and then perform processes such as decoding and decryption on each encrypted data to obtain each corresponding image.
In some embodiments, when the first sub-encrypted data is processed according to an encryption algorithm in a preset first algorithm and the second sub-encrypted data is processed according to an encryption algorithm in a preset second algorithm, the processor is configured to:
decrypting the first sub-encrypted data according to a decryption algorithm in the first algorithm;
and decrypting the second sub-encrypted data according to a decryption algorithm in the second algorithm.
That is to say, the process of reading, decoding, decrypting and obtaining an image performed by the processor may be regarded as an inverse process of processing an image to be processed into encrypted data according to different encryption algorithms performed by the processor, so that an image corresponding to each encrypted data can be accurately determined, so that a user can perform a required operation on the obtained image; moreover, the operation safety can be improved, and the risk of image leakage is reduced.
Specifically, in the embodiment of the present invention, the intelligent device may further include:
a display configured to: and displaying the image corresponding to the encrypted data.
Therefore, the user can conveniently perform related operations (such as browsing, editing, deleting and the like) on the image corresponding to the decrypted data, and convenience is provided for the user.
In some embodiments, when the position information of the first area in the image to be processed is processed according to the encryption algorithm in the first algorithm to obtain the third sub-encrypted data, the processor is configured to:
according to a decryption algorithm in the first algorithm, carrying out decryption processing on the third sub-encrypted data to obtain position information of the first area in the image to be processed;
and processing the first area and the second area according to the position information to obtain an image corresponding to the encrypted data.
Therefore, the position information of the first area in the image to be processed can be obtained, and the image corresponding to the encrypted data can be accurately and effectively determined after the first area and the second area are processed according to the position information, so that the problem that the obtained image is inconsistent with the original image is avoided, and the accuracy of image processing is improved.
In some embodiments, a processor configured to:
and after the encrypted data is decoded and when the image corresponding to the encrypted data does not comprise the first area, the encrypted data is decrypted according to a decryption algorithm in the second algorithm to obtain the image corresponding to the encrypted data.
Therefore, when the image corresponding to the encrypted data does not include the first area, the encrypted data does not include the privacy information, and at the moment, the image corresponding to the encrypted data can be obtained by adopting a simpler decryption mode, so that the calculation amount and the processing amount can be reduced, the processing speed can be increased, and the decryption efficiency can be improved.
In some embodiments, when decoding the encrypted data, the decoding may be performed according to a certain decoding rule, and the encoding rule and the decoding rule may be a pair of inverse processing rules.
Therefore, the decoded sub-encrypted data can be obtained in a simple and effective mode, and the algorithm can be used for decrypting the sub-encrypted data, so that the image corresponding to the encrypted data can be obtained, the processing complexity can be reduced on the basis of ensuring the safety, and the processing efficiency can be improved.
In some embodiments, a processor configured to:
judging whether the encrypted data comprises a first preset mark or not according to a decoding rule; the first preset mark is used for indicating that the number of the first areas is larger than zero;
if yes, determining that the image corresponding to the encrypted data comprises a first area;
if not, determining that the image corresponding to the encrypted data does not comprise the first area.
That is to say, since the first preset flag indicates that the number of the first areas is greater than zero, and may specifically indicate the number of the first areas, whether the encrypted data includes the privacy information may be determined according to whether the encrypted data includes the first preset flag, that is, whether the image corresponding to the encrypted data includes the first area is determined, so that it is advantageous to determine which decryption method to decrypt the encrypted data, and finally obtain the image corresponding to the encrypted data.
Or, optionally, when the processor determines whether the encrypted data includes the privacy information, the following method may also be adopted:
judging whether the encrypted data comprises a second preset mark or not according to a decoding rule; the second preset mark is used for indicating that the number of the first areas is zero;
if not, determining that the image corresponding to the encrypted data comprises a first area;
if yes, determining that the image corresponding to the encrypted data does not comprise the first area.
Therefore, whether the encrypted data comprises the privacy information or not can be determined, so that the method is favorable for determining the decryption mode according to which the encrypted data is decrypted, and finally the image corresponding to the encrypted data is obtained.
In some embodiments, the encryption algorithm in the first algorithm corresponds to a different key than the decryption algorithm in the first algorithm;
the encryption algorithm in the second algorithm corresponds to the same key as the decryption algorithm in the second algorithm.
As shown in fig. 4, the key corresponding to the encryption algorithm in the first algorithm may be set as a public key, the key corresponding to the decryption algorithm in the first algorithm may be set as a corresponding private key, and the public key and the private key are set in a one-to-one correspondence, and if the public key is used to encrypt data, only the corresponding private key is used to implement decryption.
Therefore, the complexity of encryption and decryption can be improved, and meanwhile, the safety is improved, so that decryption cannot be performed when a corresponding private key is not available, and a corresponding image cannot be obtained through encrypted data.
Thus, the first algorithm can be understood as: an asymmetric algorithm.
As shown in fig. 4, the key corresponding to the encryption algorithm in the second algorithm may be set as a public key, and the key corresponding to the encryption algorithm in the second algorithm is also a public key, that is, the keys corresponding to encryption and decryption are the same, and the decryption process can be performed as long as the public key is provided.
In this way, since the second area has less risk to the privacy of the user, the same key can be used for encryption and decryption, so the second algorithm can be understood as a symmetric algorithm; and because the same key is adopted, the calculation amount is small, the complexity is low, and the encryption and decryption processing speed is high.
Based on this, when the image to be processed includes the first area and the second area, the first area and the position information thereof are processed by adopting the asymmetric algorithm, and the second area is processed by adopting the symmetric algorithm, that is, different areas are processed by adopting different algorithms, so that the safety of the first area can be improved, the processing speed can be improved, and the safety and the processing speed can be ensured.
In some embodiments, a key (i.e., a private key) corresponding to a decryption algorithm in the first algorithm may be stored in the external storage device, and when a user needs to decrypt, the external storage device in which the private key is stored may be inserted into the smart device, that is, the user may decrypt through the private key. And after the decryption is completed, the external storage device storing the private key can be pulled out.
Therefore, the decryption security can be improved, the protection of the data is enhanced, the data security is improved, and the leakage risk is reduced.
It should be noted that, in the embodiment of the present invention, when performing encryption processing on an image to be processed, if the image to be processed includes privacy information, then: three parts of contents are encrypted, and the three parts of contents comprise:
1. a first region;
2. position information of the first area in the image to be processed;
3. a second region.
When the encryption processing is performed on the three contents, the order of the encryption processing is not limited herein, and the encryption processing may be performed on the three contents as long as the encryption processing can be completed.
If the image to be processed does not include the privacy information, only a part of the content (i.e., the entire image to be processed) is subjected to the encryption processing.
Similarly, when decrypting encrypted data, if the encrypted data includes private information, then: similarly, the decrypting process for the three parts of content may specifically include:
1. sub-encrypted data corresponding to the first area;
2. sub-encrypted data corresponding to the position information of the first area in the image to be processed;
3. and sub-encrypted data corresponding to the second area.
When the decryption process is performed on the three contents, the order of the decryption process is not limited herein, and the decryption process may be completed on the three contents.
It should be further noted that, optionally, in the embodiment of the present invention, an encryption algorithm in a first algorithm may be further used to perform encryption processing on the first area, and an encryption algorithm in a second algorithm may be used to perform encryption processing on the position information of the second area and the position information of the first area respectively.
Correspondingly, when decryption is carried out, the decryption algorithm in the first algorithm is adopted to carry out decryption processing on the first area, and the decryption algorithm in the second algorithm is adopted to carry out decryption processing on the position information of the second area and the position information of the first area respectively.
Therefore, the encryption degree of the first area is high, the security is high, and the difficulty of being cracked is high, so that even if the position information of the first area is processed by the second algorithm with low encryption degree, the image to be processed still has high security and high processing speed.
The encryption process and the decryption process are described below with reference to specific embodiments.
And (3) encryption process: as shown in fig. 5, the following steps are executed by the processor.
