I found it - using reverse image search and getting pointed back to Ensign Kellogg -> https://memory-alpha.fandom.com/wiki/Kellogg and actress Cameron https://memory-alpha.fandom.com/wiki/Cameron

I’m sorry; no. Her name is Cameron. She was a frequent stand-in on TNG and she’s best known (I guess) for co-starring in the cult classic Samurai Cop. Her given name on the show was Ensign Kellogg and she appeared in 43 episodes and the first two films.

Patricia Tallman was in a few episodes of TNG, but OP’s pic is from “Data’s Day,” in which she did not appear. One of the three episodes she did appear in was “Power Play,” and here’s a screenshot of her in that. (This was the only episode in which she appeared as a crewmember. In all of her other appearances, she was an alien of some sort.)

While there are striking similarities, and you are probably correct, sadly I was unable to find any pictures of this scene and/or of Patricia Tallman showing this seductive smile with a touch of Audrey-Hepburn elegance. Also, the only Star Trek Episode I could find on memory-alpha fandom with Patricia Tallman as a security officer, was one where she had no bangs but a rather tously haircut: https://memory-alpha.fandom.com/wiki/Unnamed_USS_Enterprise_(NCC-1701-D)_personnel#Security_command_001

Who is that lady? Name of the actress?
