Blob Management Feature in eCatalog


Advanced Handling and Security for Document Attachments:

Blob Management is a critical feature within eCatalog designed to provide administrators with advanced tools for managing binary large objects (blobs), which typically include files such as documents and attachments. This feature is essential for maintaining security and operational efficiency, particularly in handling sensitive or large data files.


Key Capabilities of Blob Management:


  • Encryption and Decryption:
    • Secure Storage
      Administrators can encrypt attachments to ensure that they are secured at the database level. This prevents unauthorized use of the data, as encrypted files are unreadable without proper decryption keys.
    • Accessible Use
      When necessary, the system can decrypt these attachments to return them to their original state, ensuring that authorized users can access and use them as intended.
  • Compression and Decompression:
    • Space Efficiency
      To optimize storage usage, eCatalog can compress attachments using zip-compression techniques. This reduces the space required to store documents without losing any data.
    • Seamless Access
      Decompression occurs automatically when the document is accessed, ensuring that the compression is transparent to developers and users, who interact with the document as if it were never compressed.
  • Sanitization
    • Safe Distribution: 
      The sanitization tool allows administrators to cleanse documents of potentially malicious content or sensitive information before they are made available to users or external parties. This feature is crucial for maintaining document security and compliance.
    • Downloading Raw Data:
      Testing and Verification: Administrators can download the raw data of any blob, which is particularly useful for testing the effectiveness of compression or encryption. This feature allows for technical verification and troubleshooting, ensuring that all processes are functioning correctly.


Benefits of Blob Management:


  • Enhanced Data Security
    By providing robust encryption and sanitization options, Blob Management helps protect sensitive data from unauthorized access or breaches.
  • Improved System Efficiency
    Compression features reduce the amount of space required to store data, enhancing database performance and reducing storage costs.
  • Flexible Data Handling
    Administrators have the flexibility to encrypt, decrypt, compress, decompress, and sanitize documents as needed, based on organizational requirements and data policies.


Configuring Blob Management:


  • Accessible Through Administrative Dashboard
    Blob Management settings are accessible via eCatalog’s administrative interface, where administrators can manage encryption keys, set compression policies, and apply sanitization protocols.
  • Customizable Settings
    Administrators can tailor Blob Management settings to align with specific security, storage, and access requirements, adapting to the diverse needs of the organization.











Blob is a technical term of attachments/documents.


Blob Management is meant for administrators to look into the attachment detail, and more information which are not available for normal users. This page is useful for troubleshooting.



Following are actions you can perform:

  • Encrypt. System can encrypt the attachment for security on database level. Even if someone download the data directly from database, he cannot use the data because of encryption. System will need additional seconds to download encrypted document.
  • Decrypt. System decrypt the attachment back to normal attachment.
  • Compress. System can perform compression to save space. It is using zip-compression. This compression is transparent and stored on database level. Developers does not need to uncompress the attachment, because the decompression runs automatically. System will need additional seconds to download compressed document.
  • Uncompress. System can change the compressed document to normal docoument.
  • Download Raw Data. This is mainly used for testing the compression or encryption. When downloading raw data, encrypted document cannot be read.
  • Sanitize. This tool is to sanitize document.
