A system for monitoring flows of people inside a predetermined area includes at least one receiving unit with at least one antenna adapted to receiving identification data transmitted by mobile communication devices present in a monitored area, the receiving unit also provided with a device for processing the data collected by the antenna; a processing unit programmed to perform statistical processing of the data collected by the antenna and processed by the respective processing device; and a data transmission network which connects the at least one receiving unit with the statistical data processing unit. Additionally, the processing device which receives the data collected by the antenna is programmed to perform an anonymization process with compression of the data, such that the data transmitted on the data transmission network are data that cannot be related back to the individual mobile devices that have generated them.

A security processor includes a key generator circuit configured to randomly generate a key, an encryption circuit configured to encrypt user data based on the key, and a security manager circuit configured to receive a first user identification (ID), which uniquely corresponds to a user of a device, and determine whether to allow access to the user data by authenticating the first user

ID.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

The present disclosure relates to a method for sharing encrypted data comprising encrypting first data with at least one first attribute. The first attribute satisfies a first access policy of a first cryptographic key to enable one or more first users holding the first cryptographic key to decrypt the encrypted first data using the first cryptographic key. The method also comprises encrypting second data with at least one second attribute of the second data. The method further provides for generating a second cryptographic key based on a second access policy including at least one logical connective of the first attribute and the second attribute for decrypting the encrypted first data and the encrypted second data using the second cryptographic key and providing the second cryptographic key to one or more second users to enable the second users to decrypt the encrypted first data and the encrypted second data.

A cloud-based system for securely storing data, the system having a processor which obtains a source data file; splits it into at least three fragments; and uses an encryption key associated with the fragments to encrypt the fragments and distributes the encrypted fragments among at least three cloud storage providers, creates a pointer file containing information for retrieving the encrypted fragments. When a system user requests access to the data, the system uses the information stored in the pointer file to retrieve the stored encrypted fragments from the plurality of clouds; decrypts the fragments and reconstructs the data, and provides data access to the system user.

A secure element device that is configured to be cryptographically bound to a host device includes a secure element host key slot configured to store host key information that allows only the host device to control the secure element, a secure memory storing binding information, and limited functionality allowing the binding information to be read from the secure memory by the host device during a binding process. The binding information is cryptographically correlated with the host key information. The host key information is generated by the host device using the binding information read from the secure element and a secret key. The secure element device further includes general functionality only accessible to the host device using the host key information that is generated by the host device. The secure memory includes prevention measures impeding unauthorized entities from obtaining information from the secure memory.
