Temporary Email Address for Cloud Printing Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience psychological resistance when sharing their email address for a cloud printing system, as it is used permanently, hindering the widespread adoption of the convenient printing solution.
Innovation Solution
A printing system that allows setting an expiration date for email addresses associated with printers, enabling temporary use and managing these dates to prevent misuse, thereby reducing the risk of permanent address disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an email address is set as permanent for a printer, then the printing system convenience is improved, but user psychological resistance increases when sharing the address
Solution Approach 1:
The patent applies dynamics by changing the email address from a static permanent state to a dynamic temporary state with expiration dates. The email address is automatically invalidated after a predetermined period or after a single use, transforming it from a fixed resource to a time-limited one. This dynamic behavior resolves the contradiction by maintaining printing convenience while eliminating permanent disclosure risks.
Solution Approach 2:
The patent implements the disposable principle by creating email addresses that are intentionally short-lived. Each email address is assigned an expiration date or single-use limitation, making it a disposable resource rather than a permanent one. This allows users to share addresses without concern for long-term exposure, as they will automatically expire after use or a set period.
2Adaptability or versatility
If an email address is shared with third parties, then the printing system accessibility is improved, but the risk of spam and misuse increases
Solution Approach 1:
The system dynamically manages email address validity through expiration dates and usage tracking. The server automatically invalidates addresses after predetermined periods or single uses, creating a dynamic security mechanism that adapts to usage patterns. This dynamic control enables broad accessibility while continuously mitigating spam and misuse risks through automatic invalidation.
Solution Approach 2:
The patent implements feedback mechanisms where the server tracks email address usage and automatically responds by invalidating addresses after predetermined conditions are met. The system provides feedback to both users and third parties through automatic expiration, creating a self-regulating mechanism that prevents long-term misuse without requiring manual intervention.
3Device complexity
If the same email address is used continuously, then the system simplicity is maintained, but the user trust and security perception deteriorates
Solution Approach 1:
The system performs self-service by automatically managing email address expiration without requiring user intervention. The server autonomously tracks usage patterns, determines when addresses should expire, and invalidates them automatically. This self-service mechanism maintains system simplicity from the user perspective while enhancing security perception through automatic address management.
Solution Approach 2:
The patent changes the temporal parameter of email address validity from permanent to time-limited. By introducing expiration dates and usage counts as可变 parameters, the system transforms the static nature of email addresses into dynamic, time-sensitive resources. This parameter change enhances user trust and security perception while maintaining operational simplicity.

AI summary
The advantage of the invention is to prevent malicious use of a leaked e-mail address. A printing system has a printer, and a server device which causes the printer to conduct printing of print target data included in an e-mail when receiving the e-mail that designates the printer as a printing place. The printing system has an expiration date setting section that sets an expiration date in an e-mail address that uses the printer as the printing place, a mail address registering section that registers the generated e-mail address and the set expiration date by being associated with each other, and an expiration date managing section that manages the registered expiration date and disables the e-mail address whose expiration date has expired.
