    Abstract: The invention provides a secure method for exchanging entities via a blockchain. The invention incorporates tokenisation techniques, and also techniques for embedding metadata in a redeem script of a blockchain transaction. Embodiment(s) provide a computer implemented method of performing a transfer, the method comprising: generating a first exchange transaction, and broadcasting, over a first network, the first exchange transaction for inclusion on a P2P distributed ledger, wherein the first exchange transaction comprises: an indication of a first quantity of a cryptocurrency to be transferred; a first input provided from an output of a first invitation transaction from a first user, the first invitation transaction previously included on the P2P distributed ledger, a first script, a first user private key associated with the first user, a first third-party private key associated with a first third-party, and a first output indicating a transfer of a first entity from the first user to a second user; and wherein the first script comprises: a first set of metadata providing an indication of the first entity to be transferred and a first set of conditions for the transfer, a first user public key associated with the first user, the first user public key being a cryptographic pair with the first user private key, and a first third-party public key associated with the first third-party, the first third-party public key being a cryptographic pair with the first third-party private key.

    Abstract: Method for calculating a modifier code of a file, the method comprising the following steps:



    a) establishing a list of possible modifier codes;
    b) establishing a list of a plurality of possible mixer numbers;
    c) for each modifier code: i) creating a list of hashes of the file;

    ii) for each mixer number, calculating the hash of the file mixed and modified by the modifier code, the modification of the file being performed using the same modification function;
    iii) adding each hash calculated in step ii) to the list of hashes of the file;
    iv) counting the number of different elements N of the list of hashes;
    v) memorizing this number N, as well as the associated modifier code, if N is the first to be counted or is greater than the number N previously memorized; and


    d) returning the last modifier code memorized.

    Abstract: A method of generating a file hash using mount namespace data includes identifying, by a user space monitoring application executing in a user space of an operating system, a target application file associated with a target application process executing in the user space of the operating system, wherein the target application process is associated with a first mount namespace, accessing, by the user space monitoring application, a mapping between the first mount namespace and one or more processes executing in the user space of the operating system, switching, by a processing device, the user space monitoring application to the first mount namespace based on the mapping, and accessing, by the user space monitoring application, the target application file in the first mount namespace.

    Abstract: Embodiments for performing the inline deduplication by filtering streaming data as it is received by a backup client through a backup server executing a backup process. A data processing unit (DPU) is deployed to offload certain processing operations performed by a central processing unit (CPU) of the backup client. An inline deduplication operation comprises file operations, data segmentation, segment fingerprinting, compression, and encryption prior to storage in a backup target. The DPU is deployed and configured to perform the compression and encryption steps, the entire inline deduplication stack, or the entire inline deduplication stack plus the file system operations.

    Abstract: A method comprises computing a first hash value for at least one file of a plurality of files to be tiered in connection with a file tiering operation of the plurality of files from a source storage location to a destination storage location, wherein the file tiering operation comprises tiering of the at least one file to the destination storage location. In the method, the first hash value is compared to a second hash value for the at least one file, wherein the second hash value is computed from data in an object on the destination storage location corresponding to the at least one file. Based at least in part on the comparing, a determination is made whether the first hash value is the same as the second hash value. The tiering of the at least one file to the destination storage location proceeds in response to an affirmative determination.

    Abstract: In an example of an embodiment of the invention, data is replaced by a digest of the data to decrease storage requirements. When the format of the data is not known, a repeating pattern is identified within stored data comprising a plurality of data files, each data file comprising at least a header section and a data section. At least one occurrence of the repeating pattern is identified as a header section of a respective data file, and a data section of the respective data file is identified based, at least in part, on a location of the at least one occurrence of the repeating pattern. The identified data section of the respective data file is backed up. Systems are also disclosed.
