Method, apparatus, and computer program product for detecting risk tags
First Claim
1. A risk tag detector server for detecting risk tags, the risk tags being tags which are likely to be faulty, the risk tag detector server comprising:
- a tag manager interface configured to obtain a tag list comprising at least two tags to evaluate;
a tag selector configured to select a candidate tag to evaluate from the tag list;
a tag event interface configured to obtain event data of tag usage for the candidate tag; and
a fault detector, whereinthe fault detector is configured to determine whether the candidate tag is a risk tag by performing at least the following step;
determining that the candidate tag is no longer affixed to an article to which the tag was previously affixed, wherein determining that the candidate tag is no longer affixed to the article comprises determining that the event data indicates that the tag has been repetitively read by a single terminal.

Abstract
It is presented a risk tag detector server for detecting risk tags, the risk tags being tags which are likely to be faulty. The risk tag detector server comprises: a tag manager interface configured to obtain a tag list comprising at least two tags to evaluate, and to obtain tag data coupled to each of the tags of the tag list; a tag selector configured to select a candidate tag to evaluate from the tag list; a tag event interface configured to obtain event data of tag usage for the candidate tag; and a fault detector configured to determine the candidate tag to be a risk tag when a first condition is satisfied, the first risk condition comprising a first criterion that the event data indicates an absence of candidate tag usage during a predetermined time period. A corresponding method and computer program are also presented.

4. A method for detecting risk tags, the risk tags being tags which are likely to be faulty, the method comprising the steps, performed in a risk tag detector server, of:
-
obtaining a tag list comprising at least two tags to evaluate;
selecting a candidate tag to evaluate from the tag list;obtaining event data of tag usage for the candidate tag; and determining the candidate tag to be a risk tag, wherein determining the candidate tag to be a risk tag comprises determining that the candidate tag is no longer affixed to an article to which the tag was previously affixed, wherein determining that the candidate tag is no longer affixed to the article comprises determining that the event data indicates that the tag has been repetitively read by a single terminal. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A computer program product comprising a computer program for a risk tag detector server and a non-transitory computer readable means on which the computer program is stored, the computer program comprising computer program code which, when run on the risk tag detector server, causes the risk tag detector server to perform the steps of:
-
obtaining a tag list comprising at least two tags to evaluate;
selecting a candidate tag to evaluate from the tag list;obtaining event data of tag usage for the candidate tag; and determining the candidate tag to be a risk tag, wherein determining the candidate tag to be a risk tag comprises determining that the candidate tag is no longer affixed to an article to which the tag was previously affixed, wherein determining that the candidate tag is no longer affixed to the article comprises determining that the event data indicates that the tag has been repetitively read by a single terminal.
