Advanced Encryption standard is a widespread encryption method that is used for secure data transmission.

Asia-Pacific is the part of the world near the western Pacific Ocean. The Asia-Pacific region varies in area depending on context, but it generally includes Asia, Australia, and Oceania, (02.03.2022 source: https://en.wikipedia.org/wiki/Asia-Pacific)

Azure Data Lake Storage is a set of capabilities dedicated to big data analytics, built on Azure Blob Storage. (16.11.2022 Source: https://learn.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-introduction)

Blob Storage is a Microsoft’s object storage solution for the cloud. Blob storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that doesn't adhere to a particular data model or definition, such as text or binary data.

In the cloud storage environment, a bucket is a container for storing objects in a compartment. Any number of objects can be stored in a bucket. (04.05.2022 Source: https://docs.aws.amazon.com/en_us/AmazonS3/latest/userguide/UsingBucket.html)

Comma-separated values is a file format which stores tabular data in plain text form.

Dialed Dual Tone Multi Frequency keys represent dialing signals on the analog connecting cable of the telephone. This is a method to transmit the phone number to the telephone network or to a PBX.

EMEA is an abbreviation for the European Economic Area, Middle East, and Africa. However, the term is not completely clear, and while it usually refers to Europe, the Middle East and Africa, it is not uncommon for business and other institutions to slightly tweak the countries they include under this umbrella term.

File Transfer Protocol: Network protocol for file transfer

Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in a secondary region that is hundreds of miles away from the primary region. A write operation is first committed to the primary location and replicated using LRS. The update is then replicated asynchronously to the secondary region. When data is written to the secondary location, it's also replicated within that location using LRS.

HubStor is a SaaS cloud data platform that unifies backup and archive as a service, helping organizations protect their data, simplify their IT infrastructure, and achieve compliance. HubStor uniquely converges data protection, archive, cloud storage, and content indexing as a simple and reliable software service running in any major cloud region around the world.

Locally redundant storage (LRS) copies your data synchronously three times within a single physical location in the primary region. LRS is the least expensive replication option, but is not recommended for applications requiring high availability or durability.

With regard to audio compression, MP3 uses lossy data-compression to encode data using inexact approximations and the partial discarding of data. MP3 compression works by reducing (or approximating) the accuracy of certain components of sound that are considered (by psychoacoustic analysis) to be beyond the hearing capabilities of most humans. The remaining audio information is then recorded in a space-efficient manner.

MP4 is a video container format. MP4 file format is based on Apple QuickTime file format. MP4 files allow saving multimedia content as several audio and video tracks as well as subtitles, 2D and 3D graphics. This content may be replayed locally with a dedicated software or streamed via a network. (Source: Wikipedia 07.02.2020)

Encryption of files with PGP (Pretty Good Privacy)

Public Switched Telephone Network

Record on demand

RSA is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private). In RSA, this asymmetry is based on the practical difficulty of the factorization of the product of two large prime numbers, the "factoring problem". [1] A user of RSA creates and then publishes a public key based on two large prime numbers, along with an auxiliary value. The prime numbers must be kept secret. Anyone can use the public key to encrypt a message, but with currently published methods, and if the public key is large enough, only someone with knowledge of the prime numbers can decode the message feasibly.

Secure File Transfer Protocol (SFTP) has been created for Secure Shell (SSH) as an alternative to the File Transfer Protocol (FTP) allowing encryption.

Time to live is the retention period indicating for how long a recording is supposed to be held available in the system.
