And the access control equipment obtains at least one of the characteristic data of each dimension of the entity object, such as color, weight, size, form, internal structure, physical composition and the like according to the scanning data. The entrance guard control equipment takes at least one of dimensional characteristics such as color, weight, size, form, internal structure and physical composition of the entity article as field characteristic data of the entity article.

And step 206, acquiring the scanning time of the access control detector for entity scanning.

The scanning time refers to a time for performing entity scanning on an entity article, and the scanning time may include a year, a month, a date, a time, and the like. For example, the scanning time is 11 o' clock 20 min at 8/12/2020.

Specifically, when the access control device performs entity scanning on an entity article through the access detector, the scanning time of the entity scanning is recorded. Further, the access control device may use a time when the entity scanning is started as the scanning time, or may use a time when the entity scanning is completed as the scanning time.

208, when the field characteristic data is matched with the registered characteristic data and the scanning time is within the service life of the registered characteristic data, controlling an access controller corresponding to the access detector to execute an access opening action; the registration characteristic data is characteristic data obtained by scanning the entity certificate object.

Specifically, the user registers the entity certificate object to use the registered entity certificate object for controlling access control. And the access control equipment performs entity scanning on the entity certificate object through the access detector to obtain the registration characteristic data of the entity certificate object. And the access control equipment registers the entity certificate object according to the registration characteristic data, sets the service life of the registration characteristic data, and stores the registration characteristic data and the service life in a correlation manner.

And after the access control equipment acquires the field characteristic data of the entity article, acquiring the registration characteristic data corresponding to the entity voucher object. And then, the access control equipment compares the field characteristic data corresponding to the entity article with the registered characteristic data, and compares the scanning time with the service life corresponding to the registered characteristic data. And when the field characteristic data and the registration characteristic data are matched and the scanning time is within the service life of the registration characteristic data, determining that the entity article is a registered certificate object and is within the validity period. And the access control equipment controls the access controller corresponding to the access detector to execute the access opening action so as to open the access.

In this embodiment, the access control device may compare the field characteristic data corresponding to the physical object with the registered characteristic data, and compare the scanning time with the service life corresponding to the registered characteristic data when the field characteristic data matches the registered characteristic data.

In this embodiment, the access control device may compare the scanning time with the service life corresponding to the registration feature data, and compare the field feature data corresponding to the entity article with the registration feature data when the scanning time is within the service life corresponding to the registration feature data.

In the access control method, any entity certificate object is registered to be used as a temporary certificate for access control. And performing entity scanning on the entity object to be verified to obtain the characteristics of the entity object, and comparing the characteristics of the entity object with the characteristics of the registered entity certificate object so as to judge whether the entity object is registered. And determining whether the scanning time of the entity item is within the service life of the registration characteristic data so as to determine that the registration information of the entity item is within the valid service life.

The item identifier refers to a unique identifier for characterizing a single item, such as, but not limited to, characterizing the item identifier by a barcode, a two-dimensional code, and the like.

Specifically, when the access control device detects the physical object in the detection range through the access detector, the access control device detects and scans the object identifier of the physical object through the access detector.

For example, the article identifier may be a barcode, a two-dimensional code, or the like pasted on or imprinted on the surface of the physical article, or may be a chip built in the physical article, such as an NFC (Near Field Communication) chip. The entrance guard detector can obtain the article identification of the entity article by scanning the bar code or the two-dimensional code on the surface of the entity article. Or, the access detector may obtain the item identifier of the physical item by detecting an NFC chip inside the physical item.

Further, when the field characteristic data of the entity article includes color, size, form, internal structure and physical composition, the access control device converts the color, size, form, internal structure and physical composition into corresponding vectors, thereby obtaining the field characteristic vector of the entity article.

For example, the color, weight, size, shape, internal structure and physical composition of the physical object are converted into the numerical values D1, D2, D3, D4, D5 and D6, and the feature data of the several latitudes can define the field feature vector as D [ D1, D2, D3, D4, D5, D6 ].

And step 304, acquiring a registration feature vector corresponding to the registration feature data.

Specifically, the access control device obtains a registration feature vector corresponding to the entity credential object. Wherein, the entity certificate object refers to the registered entity article.

Step 306, determining the similarity between the field feature vector and the registered feature vector.

Specifically, the access control device may be configured to determine similarity between the field feature vector and the registered feature vector, where the similarity may be cosine similarity, linear similarity, or the like. For example, the entrance guard control device may calculate the similarity between the field feature vector and the registered feature vector by a cosine similarity formula:

wherein the content of the first and second substances,

is the pre-similarity of the physical object and the physical voucher object.

Is the corresponding on-site feature vector of the entity article,

and the corresponding registration feature vector of the entity certificate object.

And step 308, determining a matching result of the field characteristic data and the registered characteristic data according to the similarity.

And determining a matching result of the field characteristic data and the registered characteristic data according to the similarity and the similarity threshold comparison result.

Further, when the similarity is larger than the similarity threshold, the field feature data and the registered feature data are judged to be matched. And when the similarity is less than or equal to the similarity threshold, judging that the field characteristic data and the registered characteristic data are not matched.

In this embodiment, the feature data is converted into corresponding feature vectors, and according to the similarity between the field feature vectors and the registered feature vectors, whether the field feature data and the registered feature data are matched can be accurately determined, so that whether the entity article and the registered entity certificate object are the same object is determined, and corresponding access control operation is executed.

FIG. 4 illustrates a process for authenticating a physical object in one embodiment. When the entity article is in the detection range of the entrance guard detector, the entrance guard control equipment performs entity scanning through the entrance guard detector so as to perform entity scanning. Through entity scanning, the access control equipment obtains the field characteristic data of the entity article. And the access control equipment acquires the scanning time of the access detector for entity scanning. And then, the access control equipment transmits the field characteristic data and the scanning time of the entity article to a background. And the background acquires the stored registered feature data, determines whether the field feature data is matched with the registered feature data, and determines whether the scanning time is within the service life of the registered feature data.

Further, the background converts the field characteristic data into a field characteristic vector, acquires a registration characteristic vector corresponding to the registration characteristic data, and calculates the similarity between the field characteristic vector and the registration characteristic vector. And if the similarity is greater than the similarity threshold, judging that the field characteristic data is matched with the registered characteristic data. And if the similarity is less than or equal to the similarity threshold, judging that the field characteristic data is not matched with the registered characteristic data.

And when the field characteristic data is not matched with the registered characteristic data, keeping the entrance guard locked. And when the scanning time exceeds the service life of the registered feature data, keeping the entrance guard locked.
