GENERATING SEARCH DATABASE BASED ON EARTH'S MAGNETIC FIELD MEASUREMENTS |
| 摘要 |
There is provided a database entity for generating a search database, comprising: at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the database entity at least to: acquire, from each of the plurality of mobile devices, an indication of at least one object; acquire a reference Earth's magnetic field, EMF, fingerprint representing at least one of magnitude and direction of the EMF in a location and/or environment to which the at least one object is related to; associate each object with the corresponding reference EMF fingerprint; and generate a database of associations between the reference EMF fingerprints and the objects. |
