Mistaken Transmissions and Encrypt Attachments

TOKYO, Japan (February 14, 2017) – Digital Arts Inc. (headquartered in Chiyoda-ku, Tokyo, Japan; CEO Toshio Dogu; “Digital Arts”; Code 2326), a provider of information security software and solutions, announced the availability of the latest edition of m-FILTER MailAdviser, a client email security software for corporate clients as well as, government agencies and local municipalities. m-FILTER MailAdviser Ver. 3.3, available in mid-March, comes with its trademark features to prevent wrong transmissions and dramatically enhanced user operability to encrypt attachments.

Sending emails to the wrong recipient is a common human error in both private corporations and public offices. There are also frequent leak incidents of sensitive information that result from mistaken transmissions. Not only does it require a long time to recover lost credibility and reputation, loss of important data can leave immense negative impact on the business. In November 2016, IPA renewed its Guideline for SME Information Security, where it specifically states to “not include confidential or sensitive information assets in the message body. These information must be sent as encrypted attachments” as an effective provision against data loss by intercepting information mentioned under the Email Section of Sample Information Security Policies.

In response to the growing demand of data loss preventive measures as a result of sending emails to the wrong recipient, the latest m-FILTER MailAdviser update dramatically enhances features to prevent mistaken delivery and encrypt attachments.

Keyword detection feature on m-FILTER MailAdviser Ver. 3.3

With its enhanced features, users are now able to confirm on a popup dialog potentially problematic keywords found in the message body, subject field, and attachment file names, even if they have not been registered in advance by the user as a detection rule. If m-FILTER MailAdviser detects keywords that are already registered as a detection rule, it will display a popup message (“warning” or “forbid send”-- forbid send emails cannot be sent until the keyword is resolved). Users can also confirm relevant detection rules on the pop-up dialog. In addition to ensuring that selected keywords are not used in the subject field and message body, these enhanced features also reduce the risk of attaching wrong files, realizing a powerful protection when sending important files electronically.

The enhanced Encrypt Attachment feature^*1 now supports AES encryption^*2, a standard required in the CRYPTREC Ciphers List, for zipped attachments. User or administrators can select to apply AES-256 encryption for each sent message or by department, realizing flexibility to support department policies that require high levels of security. Furthermore, users now automatically receive a separate email with a zip password after sending a zipped attachment.

Other features in the latest update adds support for 64 bit edition together with the classic 32 bit edition of Microsoft Outlook. Users are no longer required to reinstall Microsoft Office if only the 64 bit edition is preinstalled in his computer.

Digital Arts strives to strengthen the m-FILTER family by responding to various customer demands on preventing wrong email transmissions, archives and spams in order to stop data leak from within.
