Abstract: A client device for storing a data set in a database is provided. The data set includes a plurality of initial data elements. The client device is configured to determine a storage location of the database for each initial data element and to obtain storage location configuration information based on the storage location. The client device is further configured to process, based on the storage location configuration information, each initial data element of a first subset of the plurality of initial data elements into a processed data element using one or more data processing operations and to transmit a modified data set to a data storage server for storing the modified data set in the database, wherein the modified data set comprises the processed data elements in the first subset and unprocessed initial data elements in a second subset which is complementary to the first subset.

Abstract: A client device configured to store data in a database of a data storage server is provided. The data storage server stores security sensitive data in one or more encrypted data structures of the database. The client device is configured to determine whether data to be stored in the database comprises security sensitive data to be stored in an encrypted data structure of the database and to encrypt this security sensitive data with an encryption key. Furthermore, the client device is configured to provide the data, including the encrypted security sensitive data, and an identifier of the encryption key to the server for storing, based on the identifier of the encryption key, the security sensitive data in the encrypted data structure of the database. According to the present disclosure, the security sensitive data which is already encrypted at the client device improves a secure protection of the data.

Abstract: A data storage arrangement includes a memory and a controller, where the controller receives an indication of data to be anonymized. The controller further parses a data element to be stored and generates a copy of one or more data portions to be anonymized. The controller further deletes one or more data portions to be anonymized to generate a modified data element to be stored. The controller further generates a copy of the modified data element to be stored utilizing deduplication. The data storage arrangement thus takes in account data anonymization during deduplication (i.e. an anonymization aware deduplication).
