Abstract

A method, system and computer program product for detecting allergens present in a product. A tag (e.g., passive RFID tag) receives a query from the user of a computing device containing a list of allergens to determine if an allergen is present in the product (e.g., product for ingestion). Product information associated with the product in stored in secure memory (e.g., write-only memory) on the tag. The tag determines if an allergen to the user is present in the product using the list of allergens in the query as well as the product information associated with the product. The tag then notifies the user of the computing device regarding whether an allergen to the user is present in the product based on the determination. In this manner, allergens are detected in a product and made known to the user.

Claims

1. A method for detecting allergens present in a product, the method comprising:

receiving, by a tag associated with said product, a query containing a list of allergens to determine if an allergen is present in said product, wherein product information associated with said product is stored in a memory of said tag, wherein said product information can only be read internally by said tag but not externally by any device;

determining, by a processor of said tag, if said allergen is present in said product using said list of allergens and said product information associated with said product; and

notifying, by said tag, a computing device of a user regarding whether said allergen is present in said product based on said determination.

2. The method as recited in claim 1, wherein process information associated with said product is stored in said memory of said tag, wherein said process information can only be read internally by said tag but not externally by any device.

3. The method as recited in claim 2 further comprising:

determining if said allergen is present in said product using said list of allergens, said product information associated with said product and said process information associated with said product.

4. The method as recited in claim 1, wherein said query comprises a non-mutable identifier.

5. The method as recited in claim 4 further comprising:

notifying said computing device of said user that said user has exceeded a maximum number of queries in response to a number of queries associated with said non-mutable identifier exceeding a threshold number of times over a period of time.

6. The method as recited in claim 1, wherein said notification indicates one of the following:

presence of said allergen in said product, a likely presence of said allergen in said product, and no presence of said allergen in said product.

7. The method as recited in claim 1, wherein said tag is attached to one of the following:

said product, a container of said product and a store shelf.

8. The method as recited in claim 1, wherein said product is selected from the group consisting of a product for ingestion, a dietary product and a wearable article.

9. A computer program product for detecting allergens present in a product, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising the programming instructions for:

receiving, by a tag associated with said product, a query containing a list of allergens to determine if an allergen is present in said product, wherein product information associated with said product is stored in a memory of said tag, wherein said product information can only be read internally by said tag but not externally by any device;

determining if said allergen is present in said product using said list of allergens and said product information associated with said product; and

notifying, by said tag, a computing device of a user regarding whether said allergen is present in said product based on said determination.

10. The computer program product as recited in claim 9, wherein process information associated with said product is stored in said memory of said tag, wherein said process information can only be read internally by said tag but not externally by any device.

11. The computer program product as recited in claim 10, wherein the program code further comprises the programming instructions for:

determining if said allergen is present in said product using said list of allergens, said product information associated with said product and said process information associated with said product.

12. The computer program product as recited in claim 9, wherein said query comprises a non-mutable identifier.

13. The computer program product as recited in claim 12, wherein the program code further comprises the programming instructions for:

notifying said computing device of said user that said user has exceeded a maximum number of queries in response to a number of queries associated with said non-mutable identifier exceeding a threshold number of times over a period of time.

14. The computer program product as recited in claim 9, wherein said notification indicates one of the following:

presence of said allergen in said product, a likely presence of said allergen in said product, and no presence of said allergen in said product.

15. The computer program product as recited in claim 9, wherein said tag is attached to one of the following:

said product, a container of said product and a store shelf.

16. The computer program product as recited in claim 9, wherein said product is selected from the group consisting of a product for ingestion, a dietary product and a wearable article.

17. A tag, comprising:

a memory unit for storing a computer program for detecting allergens present in a product; and

a processor coupled to the memory unit, wherein the processor is configured to execute the program instructions of the computer program comprising;

receiving a query containing a list of allergens to determine if an allergen is present in said product, wherein product information associated with said product is stored in a memory of said tag, wherein said product information can only be read internally by said tag but not externally by any device;

determining if said allergen is present in said product using said list of allergens and said product information associated with said product; and

notifying a computing device of a user regarding whether said allergen is present in said product based on said determination.

18. The tag as recited in claim 17, wherein process information associated with said product is stored in said memory of said tag, wherein said process information can only be read internally by said tag but not externally by any device.

19. The tag as recited in claim 18, wherein the program instructions of the computer program further comprise:

determining if said allergen is present in said product using said list of allergens, said product information associated with said product and said process information associated with said product.

20. The tag as recited in claim 17, wherein said query comprises a non-mutable identifier, wherein the program instructions of the computer program further comprise:

notifying said computing device of said user that said user has exceeded a maximum number of queries in response to a number of queries associated with said non-mutable identifier exceeding a threshold number of times over a period of time.
