Email Attachment File Classification Information Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current file classification information retention technologies face challenges in preserving and accessing metadata attributes when files are attached to emails, as this information is often lost or inaccessible due to different storage formats and locations, especially when stored externally.
Innovation Solution
A method for file classification information retention that involves determining whether to extract and store file classification information for email attachments, using APIs to retrieve information from internal or external storage, and associating it with the email through MAPI properties, ensuring accessibility for applications like data loss prevention and archive management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If file classification information is stored externally (cloud-based storage, database storage, file system Alternate Data Stream), then storage flexibility and scalability are improved, but accessibility and reliability of the information are worsened when files are attached to emails
Solution Approach 1:
The patent segments file classification information into two parts: (1) a reference identifier stored externally in flexible storage systems, and (2) the actual classification data embedded within the email message body. This segmentation allows the system to maintain storage flexibility for large classification datasets while ensuring reliability by including essential classification information directly in emails.
Solution Approach 2:
The patent introduces an intermediary mechanism (email message with embedded classification information) that bridges the gap between external storage systems and email attachments. The email serves as a mediator that carries classification information in a universally accessible format, allowing applications to access classification data without direct connection to external storage systems.
2Ease of manufacture
If file classification information is stored in different formats and locations by different applications, then application-specific optimization is improved, but compatibility and accessibility across applications are worsened
Solution Approach 1:
The patent implements a universal email-based classification information storage mechanism that can be accessed by multiple applications (data loss prevention, anti-virus, encryption, archive management). The email message serves as a universal container that different applications can read and process according to their specific needs, maintaining both application-specific optimization and cross-application compatibility.
Solution Approach 2:
The patent changes the storage parameter from application-specific formats and locations to a standardized email message format with structured classification information. This parameter change enables different applications to access classification information through a common interface while maintaining their own processing optimizations.
3Reliability
If file classification information is extracted and stored in association with emails, then information accessibility and reliability are improved, but system complexity and processing overhead are worsened
Solution Approach 1:
The patent performs preliminary extraction and embedding of file classification information into email messages at the time of email creation or file attachment. This preliminary action ensures that classification information is immediately accessible when needed, reducing the need for complex real-time retrieval systems and minimizing processing overhead during email handling.

AI summary
Techniques for file classification information retention are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for file classification information retention comprising receiving an indication of creation of an email attachment, determining, using at least one computer processor, whether to extract file classification information for the email attachment, and in the event file classification information is extracted, storing the extracted file classification information in association with the email.
