    摘要： A method to control the display of content on a screen connected to a processing platform, the content including access conditions, and the method including acquiring an image within a sensitive area, the sensitive area being an area within which content displayed on the screen would be within the field of view of an observer placed thereat, detecting a number of potential observers within the sensitive area, acquiring a number of credentials from the detected observers within the sensitive area, if the number of credentials is below the number of detected observers, disabling the display of the content, if the number of credentials equal the number of detected observers, comparing each credential with the access conditions and if all credentials match the access conditions, enabling display of the content.

    摘要： The present invention aims to improve data protection against illegal access by a strong differentiation of the security level specific on a type of data so that when the protection on a part of the data is violated, the remaining data are still inaccessible. A method for controlling access, via an open communication network, to user private data, comprising steps of: dividing the user private data into a plurality of categories, each category defining a privacy level of the data, encrypting the user private data of each category with a category key pertaining to the category of the data, attributing to a stakeholder an entity configured for accessing to at least one category of user private data, and authorizing the access to the at least one category of user private data for the entity of the stakeholder, by providing the stakeholder with the category keys required for decrypting the user private data of the corresponding category.

    摘要： A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.

    摘要： A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.
