A method for identifying content, preferably media content for publishing by a watermarking system, said system comprising a user terminal of a user, a local cluster comprising a local server and a global cluster comprising a global watermark generation device and a watermark resolution server, wherein said local cluster and global cluster being connected via a network said method comprising the steps of a) Marking a content element with a global mark by said global watermark generation device, b) Marking the content element having said global mark with a local mark by said local server in said local cluster wherein the local mark comprising location information of presentation means said content element being presented with at a location of said user terminal and additional local information including local temperature, local crowd density, local dwell time and/or local noise level sensed by at least one local sensor being connected to the local server, c) Presenting the marked content element to said user terminal at said location, d) Detecting at least part of the presented content element by said user terminal, e) Extracting the global mark and the local mark from the detected part of the content element by an application running on the user terminal, e1) Providing the extracted global mark and the extracted local mark to a watermark resolution server, e2) Identifying the provided global mark by said watermark resolution server resolving the global watermark against a global watermark database, e3) Providing, by the watermark resolution server, the provided local mark to a local watermark resolution server, f) Identifying the extracted local mark by said local watermark resolution server resolving the local mark against a local watermark database and extracting said additional information g) Providing the identified local mark and said additional information to the watermark resolution server, h) Extracting the additional local information by said watermark resolution server, i) Identifying the content element based on the identified global mark and local mark, and j) Providing an additional global and/or local content element based on the identified content element and based on evaluated extracted additional local information a) Marking a content element with a global mark by said global watermark generation device, b) Marking the content element having said global mark with a local mark by said local server in said local cluster wherein the local mark comprising location information of presentation means said content element being presented with at a location of said user terminal and additional local information including local temperature, local crowd density, local dwell time and/or local noise level sensed by at least one local sensor being connected to the local server, c) Presenting the marked content element to said user terminal at said location, d) Detecting at least part of the presented content element by said user terminal, e) Extracting the global mark and the local mark from the detected part of the content element by an application running on the user terminal, e1) Providing the extracted global mark and the extracted local mark to a watermark resolution server, e2) Identifying the provided global mark by said watermark resolution server resolving the global watermark against a global watermark database, e3) Providing, by the watermark resolution server, the provided local mark to a local watermark resolution server, e1) Providing the extracted global mark and the extracted local mark to a watermark resolution server, e2) Identifying the provided global mark by said watermark resolution server resolving the global watermark against a global watermark database, e3) Providing, by the watermark resolution server, the provided local mark to a local watermark resolution server, f) Identifying the extracted local mark by said local watermark resolution server resolving the local mark against a local watermark database and extracting said additional information g) Providing the identified local mark and said additional information to the watermark resolution server, h) Extracting the additional local information by said watermark resolution server, i) Identifying the content element based on the identified global mark and local mark, and j) Providing an additional global and/or local content element based on the identified content element and based on evaluated extracted additional local information
