The requested multimedia type may be streaming video or still image, for example. The requested multimedia criteria may comprise, for example, certain authenticity value, certain authenticity level, certain location, time, event or object. Other users of the system and registered to the server apparatus may capture the requested multimedia data using a user apparatus or a multimedia device and deliver the multimedia data to the server in response to the task.
The requested task may relate to a certain geographical area. For example, the desired multimedia data may relate to an event taking place in certain geographical location.
In an embodiment, the task may be provisioned to a group of users based on certain criteria. For example, the task may be provisioned to certain users that are assumed to be located close to the geographical area of the requested task. In such cases, hotspot information may be used in task provisioning. The task may be provisioned to certain users defined by the task creator by selecting the users.
In an embodiment, a task may be provisioned to users that are located in a certain geographical location. Second users providing multimedia data to such task may be required to provide the geographical location for the captured multimedia data. The location information may be input to the metadata of the multimedia data submitted to the task. The location information may be checked by the system when receiving the data and approving only multimedia data fulfilling the location requirement for the task. The location requirement for the task may be defined with a certain threshold i.e. the location information of the multimedia data should be within certain geographical area defined by the criteria.
In an embodiment, a new task may be received by the system and the task information is stored to the server. The task comprises criteria for the requested multimedia data, set by a first user defining the task. The criteria may relate to a location for the multimedia data, for example. The task may be responded by at least one second user providing multimedia data for the task. The first user defining the task may define if all multimedia data received for the task will be approved or if the first user will approve the multimedia data before being available for third users. Furthermore, the first user may define if the multimedia data are available to third users right after receiving the data or after the task being expired. Such settings may be included in the task criteria. There may be a plurality of tasks available at the server defined by at least one first user.
In an embodiment, the multimedia data provided by the second users for the tasks defined by the first users are available for third users.

Thus it is possible to verify the authenticity of user generated content quickly and efficiently. In an embodiment, the verification process displays each uploaded image with a graphical tag depicting scores ranging from 1-5 based on key authentication factors. Authentication has now become part of the editing process.
To uphold the highest standards of accuracy, many journalistic institutions are spending hours in an ongoing effort to ensure image authenticity, often under deadline pressure. In a world where every second counts, media companies do not have the time or resources to manually verify every image they want to publish. Time and labor aside, manual inspection methods cannot mitigate the risk of manipulated images. For this reason, the embodiments of the present disclosure show instantly and graphically the authenticity level of any user-submitted image to media companies, for example. The system basically substitutes an inherently flawed manual process that may take an hour per image for a highly-automated, intelligent program that takes seconds.
In an embodiment, images may achieve a top authenticity score if they are taken with a proprietary mobile application, not imported from the mobile apparatus photo gallery. This scenario guarantees that the photo has not been removed from the proprietary service ecosystem and the image has not been edited or altered in any way. Each pixel of the photo file is transferred as captured by the mobile apparatus (such as a mobile phone) camera. The authenticity program, as described by different embodiments of the invention, works by automatically analyzing images against a plurality of criteria ranging from image resolution to the likelihood that the photo's metadata has been modified. If further authentication is required, the system provides access to the photographer's contact information, for example.
While manual verification may still play a crucial role in user generated content (UGC) workflow, media companies, with the increasing volume of content, need cutting edge tools to verify visual content. The described authenticity system saves media groups time and money while safeguarding accuracy and improving the competitive edge.
